I have an older Harman P68. It has always worked like a champ other than a few replacement parts over the years. I cleaned it thoroughly this fall and started it up. It was working fine until this past weekend. I noticed it didn't seem to be reacting to the room temperature as it should. After some checking over I found the status light is blinking 2 times. I shut down and unplugged the stove and it seemed to reset. After a time it began flashing again. I began researching and found it relating to a jumper on the board at location J2. I removed the board and found that J2 did not have a jumper on it but a wire. I traced the wire to the vacuum switch. So I bypassed the vacuum switch. Still receiving the same error. I then pulled the control panel again and I unplugged the wire put a jumper on the J2. Still the same issue. There seems to be little information on this error. Any help would be appreciated. Cold weather is a comin'.

It seems some manuals make mention of this and others don't. I hope someone has some advice. Cold weather is coming.

Stove in two blink status Stoves with a feeder position micro switch, check for proper operation of the micro-switch. Stoves without a feeder position micro-switch check for missing or loose jumper at J2 on the control board. The stove will not shut down while in a two blink status error.
If the wire from J2 was connected to the vacuum switch, and your stove doesn't have the micro-switch, I would try a new vacuum switch and/or check tube and barb. The wire is trying to receive info from the switch and is obviously not getting it ... I don't know if by-passing the vacuum switch would change that error.

Perhaps I traced it wron and the wire is going to the micro switch. I'll need to check that tonight when I get home. Thanks for your input.
Well on top of everything else I have the model number wrong. I have a P61 not a P68. I'm not sure this makes a difference.
Anyone have any new information on this issue? I still have the same issue going on. The stove didn't run quite right all last winter. I've replaced the vacuum switch, the micro switch, I've thoroughly cleaned the stove. A Harman dealer told me the newer stoves don't even have a micro switch. I'm really frustrated with this issue.
