Pellet stoves are some of the cleanest and most efficient of all burning stoves. However, even a pellet stove sometimes can get a little clogged, so you may need to do a little troubleshooting on occasion. Before you call a repairman, do a little work on your own to save time and money.
Check the electricity source. There's only one moving part to a pellet stove--the motor--so determine whether power is getting to that unit. Test the socket it's plugged into with your voltage tester. If there's no power, a circuit breaker must be reset. If there is power but no motor running, or if the motor is running but sounds weak, turn off the power.
Remove the motor. Generally, most pellet stoves' motors are mounted behind the unit, so you'll have to get behind the stove to remove the actual motor. It will be held on by three or four screws, so use your screwdriver to remove them.
Check out the fan blades. Pull out the motor; you'll notice that it's just a large fan that blows air through the stove, sending heat into the room. Spin the blades. If the blades barely spin or don't spin at all, the bearings are bad and the motor must be replaced.
Reset the motor. If the blades spin, check the bottom of the motor for a red reset button. Push in the button, and the pellet stove will almost certainly work when you turn on the power.
Clean off the fan blades. If the motor is still running but sounds weak, chances are the fan blades are dirty and not pushing very much air through them. Use a utility brush to brush off the fan blades.
Reinstall the fan motor using your screwdriver. Replace the screws, and your stove should be good to go.
Fix the feeder. If the motor is running but there's no heat, you have a feeder problem. There will be a little door into which you pour the pellets. This door might be stuck or jammed closed. Make sure the feeder door opens and closes. If it's jammed, unjam it. If it doesn't open or close smoothly, spray your lube on the side hinges. Move the door up and down a few times, and it should work fine.
