I bought a nonworking but in otherwise great condition heatilator cab50 pellet stove. I have experience with a cab30, know my way around wiring and likeed the other stove, figured it would be an easy fix.
I plugged it in, no call light, nothing happened. I jumped the therostat connection, got a call light, it starts up.
The exhaust fan starts, looking good... does not feed pellets. I figured out someone had messed with the reset switch and pulled a wire out of the switch. They made a jump wire to bypass it and the jump wire was disconnected.
I plugged in the jump wire and it starts the start sequence, the ingniter starts it sends pellets and after a few minutes the fire starts.
A few minutes later the stove stops as there are no pellets left in the pot. If I restart it and press the reset once in a while it will send more pellets and keep the fire going and get hot enought to start the fan to circulate the air in the room. As soon as it is out of pellets it dies.
I have checked all three snap discs, the switch on the lid, the vaccum switch. All motors work. Opened all inspection plates cleaned it all and put back together.
The call light is lit and stays lit.
Near as I can tell the computer is not reading the thermocouple correctly as the green light saying it is at temp never lights up. I have tested the thermocouple and with a fire seen it make over 16 milli volt. With the wires unhooked comp has a red light saying it is too hot. Hook up thermocouple and the light goes out. Mess with the wire enough and the orange light start flashing telling me thermocouple has problems, which in that case i agree as i am hooking and unhooking it. Also noteworthy that as I hook and unhook the thermocouple wires the green light does flash very momentarly.
Removed comp and tested the thermocouple contacts at the comp, it reads correctly. Replaced both thermocouple and comp with no change.
At this point I have to be missing something simple. Any thoughts?
