Why Is My Deer Feeder Not Spinning

Start Here: The Two Things That Stop 90% Of Feeders

Your deer feeder is not spinning because the battery is weak or the spinner plate is jammed.

I fix most “dead” feeders in 10 minutes by swapping a fresh 6V or 12V battery and then checking for corn wedged between the spinner plate and the motor shaft.

Back in September 2019 on my Pike County, Illinois lease, I drove 42 minutes after work thinking my feeder motor died.

It was a $19 battery that read 5.7V under load and a single pebble wedged in the plate.

Here is what I do before I buy a new motor or timer.

I pull the spinner plate, dump the last corn, and test voltage while the unit is trying to spin.

Decide If You Have Power Or A Mechanical Jam

You have to pick a lane first.

Either the motor is not getting power, or it is getting power and can’t turn.

Here is what I do.

I set the timer to “test” and listen for a hum, then I watch the spinner plate while I tap the funnel with my knuckles.

If I hear nothing, I chase power.

If I hear a hum or a click, I chase a jam or a weak motor.

I learned the hard way that guessing gets expensive.

I wasted money on a replacement motor in 2016 for a feeder on the edge of the Missouri Ozarks, and the real problem was a corroded battery terminal.

Mistake To Avoid: Testing The Battery With No Load

A battery can look fine until you ask it to work.

A 6V battery that reads 6.2V sitting there can drop to 4.9V the second the motor tries to spin.

Here is what I do.

I put a cheap multimeter on the battery posts while the feeder is in “test” mode and I watch the voltage during the spin attempt.

If it drops hard, I replace the battery even if it “tested good” at the house.

In the Upper Peninsula Michigan, cold mornings made this worse for me.

At 18 degrees a battery that was fine in my garage acted dead on stand site.

Tradeoff: 6V Versus 12V Setups

6V systems are simple and common, but they get finicky as the battery ages.

12V systems usually spin harder and tolerate a little more drag, but the wiring is one more thing to corrode.

My buddy swears by 12V only, but I have found a clean 6V setup works fine if you keep connections tight.

If you are hunting the Missouri Ozarks on public land, I would not haul a heavy battery deep unless I have to.

On a Pike County, Illinois lease where I can drive closer, I do not mind a bigger battery and a solar panel.

Check The Obvious Stuff That Bites Guys Every Year

This stuff sounds dumb until it happens to you.

I have done all of it.

Is The Timer Actually In “On” And Not “Off” Or “Program”?

Some timers will show a screen but never fire if they are still in program mode.

Here is what I do.

I hit the manual test button and I watch the LED or screen change while I listen for the relay click.

Are Your Spade Connectors Loose Or Green With Corrosion?

That green fuzz is a power killer.

I pull each connector, scrape it clean, pinch it tighter with pliers, and hit it with dielectric grease.

Is A Critter Chewing Your Wire?

Raccoons and squirrels will chew wire insulation like it is candy.

I have seen it in East Texas around feeders and in southern Missouri around mineral sites.

Mechanical Problems: Decide If It Is Bridging, Caking, Or A True Jam

If the motor hums but the plate does not move, you are in mechanical land.

You have to decide what is stopping it.

Bridging Corn In The Funnel

Corn can “bridge” and hang up like a dome inside the funnel.

Here is what I do.

I smack the side of the hopper twice and I run the test again, then I pour the feed into a bucket and check for clumps.

Wet Feed Caking Like Concrete

Rain and humidity turn cheap corn into a brick.

This connects to what I wrote about where deer go when it rains because wet weather changes how I plan sits and how I manage feed.

If you are hunting a rainy week, forget about “set it and forget it” feeders and focus on keeping feed dry and airflow moving.

I learned the hard way that a “weatherproof” lid is not always weatherproof.

Back in October 2018 in Pike County, Illinois, I had a lid warp just enough to let a slow drip in, and the feeder acted dead for two weeks.

A Rock, Cob, Or Bolt Wedged Under The Spinner Plate

This is the most common real jam I see.

Here is what I do.

I take the spinner plate off, clear debris, and spin the motor shaft by hand to feel for rough spots.

Mistake To Avoid: Blaming Scent Control Instead Of Fixing The Feeder

I know guys who think deer “won’t come because of smell,” so they keep buying gadgets.

I wasted money on $400 of ozone scent control that made zero difference, and it sure did not fix a non-spinning feeder.

Fix the machine first.

Then worry about how you hunt it.

This connects to what I wrote about are deer smart because deer will pattern a feeder, but they will also pattern your mistakes.

Timer And Control Box Issues: Make A Call Before You Swap Parts

Timers fail, but not as often as people think.

The hard part is proving it.

Here is what I do.

I bypass the timer and run power straight to the motor for one quick test, then I know if the motor spins at all.

If the motor spins when bypassed, the timer or relay is the problem.

If it still does not spin, it is motor, wiring, or battery.

My Quick Rule of Thumb

If the feeder hums but the spinner plate does not move, pull the plate and clear a jam before you buy a motor.

If you see a big voltage drop during the “test” spin, expect the battery to fail in the next 7 days even if it charges back up.

If conditions change to wet, 38 to 55 degrees with steady drizzle, switch to dry feed storage and shorter run times so you do not cake the funnel.

Tradeoff: Run Time And Throw Distance Versus Motor Life

Long spin times feel good because you see corn everywhere.

Long spin times also kill batteries and stress cheap motors.

Here is what I do.

I run 3 to 6 seconds per throw for most whitetail setups, then I adjust based on how fast the pile disappears.

If deer are cleaning it up in one night, I add seconds.

If corn is laying there for days, I cut it back.

When I am trying to time deer movement, I check feeding times first so I am not guessing when deer will show.

Solar Panels: A Real Fix Or Just More Stuff To Break?

Solar helps, but only if you mount it where it gets sun.

If you hang a solar panel in a shaded Missouri Ozarks hollow, it is a decoration.

Here is what I do.

I mount the panel high, angle it south, and I zip-tie the cable so it cannot flap in the wind and break at the plug.

My buddy swears by cheap no-name solar kits, but I have found they die fast in heat and humidity.

I would rather run a name-brand panel and a fresh battery than chase weird charging issues all season.

Products I Have Actually Used That Fix “Not Spinning” Problems

I am not a pro guide or outfitter.

I am a guy who has burned money on junk and learned what matters.

Moultrie 6V Feeder Battery

I have used the Moultrie 6V batteries for years, and they are usually $19 to $29 depending on the week.

They are not magic, but they are consistent, and most “dead” feeders I see are just weak batteries.

DEWALT 20V MAX Cordless Drill For Cleaning And Testing

I keep a DEWALT 20V MAX drill in the truck because it saves trips.

I use it to pull screws, clean terminals with a small wire brush, and fix mounts that rattle loose and pinch wiring.

Decide If A Feeder Even Fits Your Hunting Style

I have hunted feeders in East Texas, and I have hunted places where they are a waste of time.

In Pike County, Illinois, I would rather put effort into pinch points and cold fronts than babysit a feeder.

In the Missouri Ozarks on public land, feeders are not part of my plan, and I focus on bedding cover edges and quiet access.

This connects to what I wrote about deer habitat because if your habitat is strong, a feeder is a bonus and not a crutch.

Do Not Let A Feeder Problem Turn Into A Bad Shot Problem

Guys get rushed when they finally see a deer at a feeder again.

That is how bad hits happen.

I learned the hard way that pushing a wounded deer is worse than waiting.

In 2007 I gut shot a doe, pushed her too early, never found her, and I still think about it.

If you are going to hunt a feeder, set your lanes and your yardage before you ever sit it.

This connects to what I wrote about where to shoot a deer to drop it in its tracks because shot choice matters more than any bucket of corn.

FAQ

Why does my feeder spin sometimes but not other times?

That is usually a battery that is right on the edge or a bad connection that makes contact only when it feels like it.

I replace the battery first if voltage drops under load, then I redo every connector tight and clean.

How do I tell if my feeder motor is bad?

I bypass the timer and feed power straight to the motor for one quick test.

If it still will not spin with a fresh battery and clean wiring, the motor is done.

Can corn dust stop a deer feeder from spinning?

Yes, because dust holds moisture and turns into paste that drags the spinner plate.

I dump the hopper, wipe the bottom clean, and start with dry corn.

Should I use a bigger spinner plate to fix a feeder that is not spinning?

No, a bigger plate adds load and can make a weak motor or weak battery look worse.

Fix power and jams first, then think about throw pattern.

How often should I change the battery in a deer feeder?

I change it when it drops under load or when it starts acting random, not by the calendar.

On my setups, that can be 1 season or it can be 3, depending on run time and weather.

Next Checks: Wiring, Ground, And The Stuff Nobody Wants To Mess With

If your battery is strong and the plate is clear, the next culprit is wiring and ground.

This is where I see the most “looks fine” problems that waste a whole month of hunting.

When I am trying to keep things simple for my kids, I focus on reliable setups and predictable deer movement, not constant tinkering.

This connects to what I wrote about do deer move in the wind because if the wind is wrong, I would rather move stands than blame a feeder.

Also, if you are calling every deer a “buck” in your head, it helps to be clear on terms when you talk with buddies and kids.

That is why I point people to what a male deer is called and what a female deer is called so everybody is speaking the same language.

Decide If You Are Chasing An Open Circuit Or A Weak Ground

You need to decide if power is not getting there, or if it is getting there and not returning clean.

Most feeders use the frame as ground, and that is where rust and paint will beat you.

Here is what I do.

I grab the ground wire and follow it all the way to where it bolts to metal, then I take that bolt out.

I scrape to shiny metal with a pocket knife, tighten it back down hard, and I add a star washer if I have one.

Back in August 2020 on public ground near the Missouri Ozarks, I found a ground lug screwed into painted metal.

It “worked” for a week, then one rain later it quit like a dead motor.

Mistake To Avoid: Trusting Crimp Connectors That Got Wet Once

If water gets inside a crimp, it will rot from the inside out.

It will look fine until you touch it, then it turns to green powder.

Here is what I do.

I cut the connector off, strip fresh wire, and crimp a new heat-shrink connector on it.

I learned the hard way that twisting wires together “just to get through season” turns into a dead feeder two sits later.

I did that in 2014 on a cheap setup, and it cost me an evening hunt I should have been in a tree.

Tradeoff: Quick Field Fix Versus Fixing It Right At Home

Sometimes I just want it throwing corn tonight.

Other times I want it fixed for the next 60 days with no babysitting.

If I am on my Pike County, Illinois lease and I can drive in close, I fix it right and swap parts.

If I am walking a long way, I do the fastest fix that is safe, then I rebuild the wiring at home on the bench.

Here is what I do for a quick field fix.

I clean battery posts, clean the ground, and replace only the one connector that is obviously bad.

Decide If The Motor Is Binding Or If The Gearbox Is Cooked

A motor can sound alive and still be done.

If the gearbox is stripped, it can spin free and never move the plate under load.

Here is what I do.

I pull the spinner plate, then I run the motor with no load for 2 seconds.

If it spins fast with no load but stalls with the plate on, I look for drag or a dying gearbox.

I also put my fingers on the motor housing right after a test spin.

If it is hot after 2 to 3 seconds, that motor is working way too hard.

If You Are Hunting Wet Timber, Forget “More Feed” And Focus On Keeping The Bottom Clean

In humid places, more corn usually means more dust and more caking.

That turns into drag on the plate, then battery drain, then a feeder that “randomly” quits.

Here is what I do.

I dump the last 10 pounds out once a month, wipe the funnel throat, and start clean with dry corn.

This is the same mindset I use in Buffalo County, Wisconsin hill country where little problems compound fast under pressure.

I do not give myself extra chores if I can avoid it.

One Last Reality Check: A Feeder Can Be Working And You Still Think It Is Dead

I have rolled up to a site and thought nothing was happening because there was no corn on the ground.

Then I checked the timer history and found it was throwing, but deer were cleaning it up in hours.

Here is what I do.

I rake a 2-foot circle clean under the spinner, then I come back 24 hours later to see if fresh kernels show up.

If you want to know what kind of deer are eating it, this connects to what I wrote about what a baby deer is called because fawns and does can wipe a feeder out fast in late summer.

This also connects to how much a deer weighs

My Personal Wrap Up From Too Many Dead Feeders

I have hunted 30-plus days a year for a long time, and I still get fooled by simple stuff.

The feeder “not spinning” problem is usually a weak battery, a bad ground, or junk wedged under the plate.

Here is what I do every time before I buy parts.

I test voltage under load, I pull the spinner plate, and I clean the ground to shiny metal.

I learned the hard way that throwing money at motors and scent gadgets does not fix bad connections.

If you get it spinning again, do not let the feeder become the whole plan, because deer will humble you quick.

I have found deer I thought were gone, and I have lost deer I should have found, and none of that got better because a spinner threw 2 more seconds of corn.

Keep it simple, keep it reliable, and then go hunt the wind and the sign like you would anywhere else.
