Harman 52i Issue Room Temp Issue

[Icemanxxxv]

I turned my stove on this evening. No status light illuminated. The combustion blower started no feed or igniter light illuminated. The status light flashed twice and stayed off and the stove shut down and the staus light remained out. In stove temp the status light remains on the feed and igniter light illuminates. No error codes. Waiting for the stove to light and will switch it to room temp and will post the results. This is the first time I have encountered this condition.

Check that there are no blockages in the intake piping and the flapper moves freely, have you tried unplugging it for a few minutes? Also are you using a surge protector? And how clean is the stove?

Well here is an update. The stove lit off normally in stove temp. Once it got up to temperature I switched it to room temp and it ran just fine. Being shoulder season here in Missouri the house git to the set temperature and the stove cycled off normally before we. Went to bed. Woke up this morning and the stove was operating normally. Pretty strange.

It is starting to sound like a control card problem. Maybe re-seat all the connections to the board. Double check the combustion air circuit including the blower fan area. I have yet to do this, but I am going to take the fan off the shaft and clean behind. I also want to put some anti-seize on the set screw. I am running only once and awhile now as it's in the basement, and I have heat pumps upstairs. It's still nice to have a fire in the evening, but the room heats up pretty quick.

Also, check the connections to the vac switch. I don't know the exact route of the tube that connects the pressure switch to the stove, but you might have a restriction. As you turned the stove on and off it might have cleared itself.
