Electric fireplace problem

Iíve a 2016 Winnebago Instinct 28rbds. It has a greystone electric fireplace model F2625A. On the last trip the blower would not come on. The heating element will come on but the safety switch cuts it off since thereís no air blowing. The simulated fireplace effect works.

There are some pictures below. I pulled it out and pulled the back cover off. The fan spins fine but it doesnít come on even if you spin it by hand. I do not see anything obvious out of place. I donít know if the problem is with the fan motor or the circuit board. It is out of warranty.

Any suggestions?

I haven't been able to find a schematic yet so this is just general stuff to check. Without a schematic it is hard to say exactly where to test for a 100% this is broken.

The first thing I would do is check for 120V AC across the motor and the various points along the buss bar the black wire goes through. If the voltages look good there then it is likely the motor that is bad. If you have no voltage I would chase the 120V that feeds the board to see where it fails. If the 120V going into the board is ok then I would suspect the board. There might be a fuse or breaker not showing in your pictures that could be the cause as well but I can't say for sure.

As AC motors are usually pretty reliable I would tend to think the problem being one to the relays on the board. That is just a gut feeling so please don't order parts based on that.


Be careful as 120V AC is not anything to be careless around.

Your second picture shows a non resettable safety I believe. The motor wire runs through that section. Unplug from power and check continuity through that safety with a ohm meter and see if it is open.

Thanks guys.



As to the safety, if youre talking about the thing in front of the squirrel cage, I believe that is a overtemp saftety. It connects to the fan and to the heating element. Without the fan working, it overheats real quickly and wont comeback on until it cools down.


What I did was check for 120 with my multi meter at that connection in front of the squirrel cage and where the other motor wire plugs into the circuit board. I got 120 when I engaged the heat so I'm assuming the motor is bad. I found one with like dimensions on amazon prime for $20.95 and we have amazon prime so it is free 2 day shipping. I'm hoping that will fix it.

Yes that was what I thought was the safety. The black from the fan appears to go through that. So motor more than likely as long as there is not another device on the neutral or white wire. You should be able to stick the voltmeter points into the wire at the motor to check for voltage directly at the motor. Obvious safety precautions apply.

I’m pretty sure the only other thing on that line is the heating element. I’m fairly satisfied with the splice on that white to black wire to the motor and there are no splices on the red wire. But I had already put it back together to get it out of Mrs. Dawn’s kitchen before she got home and tested the sharpness of the probes on me! Lol. The part should be in Friday so hopefully I’ll have a final verdict then.

The new part came in today. I put it in after work and reinstalled it in the camper. It fit and works. And now weíve made it to the camp ground and itís doing great. I put some pics below.
