Hi first post here, saw a lot of great info and hope someone can help. I bought a house and it has an Enviro EF2 FS pellet stove. This is my first time dealing with any kind of stove. The auger motor is not getting power. Replaced the motor, dial-a-fire switch, and timing board with a 3second timer. Verified operation of the ignitor, 120 degree switch and auto holding circuit. 160 degree switch shouldn’t have any impact on auger and the 200 degree switch looks like the red button might be out but reads at 4 ohms and I tried jumping it out. Exhaust blower is working and I also jumped out the vacuum switch. Auger does spin freely when not hooked up to motor. No obstructions. Also vacuumed out the insider the stove and exhaust the best I could. I am stumped. Anyone have any advice?
P.S. I am just going off the schematic and owner manuals I found of this site. Thanks.

Check integrity of wiring going to different points. Check to see if any wires got pinched and are now open. Be careful of ac voltage being where it shouldn't be. The TS guide provided look on page 41 and go thru the flow diagram, very valuable info there.

Does the green auger light work ?
Does the white wire at the auger timer have power (120 volt) ?

Thanks for all the info guys. I went over all the wiring again and grabbed a couple male connectors from work and made a real jumper instead of my one with alligator clips. If I jump out the vacuum switch the pellet stove runs fine. I cleaned out behind the firebox backing and found a ton of pellet ash. I also vacuumed out the exhaust at the clean out T. The motor is running and blowing air out the vent pipe but I have no idea if it is enough. Should I check the vacuum pressure before I replace the switch? And does anyone recommend a reasonably priced magnahelic gauge?

Check to make sure that where the vac hose attaches
to the exhaust passage is clear. Use a paper clip to clean
the nipple . A magnahelic gauge is more expensive that
a vac . switch . As long as the door gasket and ash pan
gasket are good then the stove should produce enough vac.
Use the dollar bill test on the gaskets

Pull the hose off the vacuum switch and blow through it and see if air passes into the chamber. Also check the tube for cracks.

I jumped out the switch and ran the pellet stove and 10 minutes later I checked and the basement started getting smoky. Maybe bad fan or dirty exhaust? I am trying everything to avoid having a tech come out. The local shop quoted me $150 just to look at it and $300 for a clean.

Maybe your smoke pipe is leaking ?
Remember this is a positive draft stove

When it gets dark start the stove and use a flashlight to look for smoke when you light it. Did you clean your chimney and check your pipe for holes? Is the appliance adapter sealed to the flue?
