Came home last night , Englander EP 25 I, was running on feed rate of 1 and fan speed of 5. The stove was still feeding and burning pellets but the convection blower was not running. I unhooked the wires from the blower and wired the blower to a 120V outlet and the blower runs fine .Ran the stove through the night this way for heat. I can;t find a schematic or wiring diagram anywhere for the EP25. I'm thinking control board or snap disc went bad but I don;t know the location of the snap disc. I can;t call Englander until business hours on Monday Any troubleshooting tips would be greatly appreciated. Thanks
convection blower shut down

PS Have you confirmed electrical connections are secure? I would suspect it is your proof of fire snap disc... It has to reach a certain temp to turn on the blower.

Thanks for the quick reply Lake Girl. I forgot about the thermal sensor,, I don;t really have a clue how to test it though. Getting ready to pull the stove out and check the wiring. Odd that there is no snap disc

Thermal sensor does the job of the snap disc... Not expensive so beyond checking electrical connections and wires, that would be my starting point.
Hello
There is not much to go wrong with the thermal or heat sensor. I did find however it the heat sensor connector is loose where it connects to the control board that will cause the problem. You can test the heat sensor in diagnostic mode to see if it is working.

Illustration 2 shows the small 3 pin connector on the end of the white rope looking heat sensor wire that may be loose.
Also check the other end to assure the bolt is tight that holds the end of the heat sensor wire on to the back of the firewall or the exhaust housing. Depends upon your model and mfd of stove as to where that end is connected

yeah, I pigtailed to an outlet and the blower ran. Figured board problem or the sensor. turned the unit on and the voltmeter read 117V.OK, so much for a board problem. I have a backup blower I put cheap bearings in and it works noisey but blowing. Going to run the original blower on the bench for awhile and see if it freezes up or overheats.
