Hello I am new to the site but not to pellet stoves. We just purchased this stove and it has ran fine for a week now. I get up this morning and the stove will not run in room temp mode. No faults and it runs fine in stove temp mode. If I unplug the room temp sensor the stove will start up. Has anybody else had this problem?
Harman p61a will not run in room temp mode.

I would contact your dealer....It is possible the probe is defective and so would be under warranty.
Was the stove by chance a floor model that has been used in a showroom for sometime previous to you taking ownership?
No it was in the box when I picked it up. I am going to call the dealer tomorrow morning. I was just curious to see if anyone else had seen this. This is our 1st Harman stove so I'm new to all of their issues.
I have a 2013 P61A and have never had a problem operating in room temp. mode. In fact, I've never run in any other setting.
By the way, is the stove set in auto or manual? If in auto, the actual room temperature may be high enough that your stove simply won't ignite as the probe is sensing a high enough temperature. Do you follow what I'm saying?
Yes. It's in auto mode it's set to around 72 to 75 degrees and it was 64 and it still would not come on. It has been working fine for a week until this morning. I will just run it on stove temp until I can have it looked at.
I would try it in manual mode just to see if that setting will operate the stove......If nothing else it will tell you if the probe works and is one less thing to explain to your dealer that you have tried. If it continues to operate when you switch over the stove should NOT shut down but only idle way down once it reaches the room temp. you have set in the stove.
Also, it will idle up and down as the probe calls for heat and tells the stove its reached the desired heat setting. Doing this should indicate if the probe works.
It will not run at all in room temp only stove temp mode. So I either have a bad probe or bad board is what it seems like. I will post what the dealer finds out.
My upgraded P61-2 to self starting (control board and igniter) works perfect in every way except it wont control room temperature. I can turn room temp knob to lowest setting and stove will just keep running at idle keeping room at 74-76 degrees depending on outside temps. I've even disconnected the room temp probe and get the "4 flashes" but stove still wont shut off. Thoughts, bad control board?
The only way to get it to shut down is to turn to "off" and unplug the stove till all motors stop, plug back in and then it will shut down. Otherwise it will run until pellets are gone
The ESP will make it do that; the motors will not stop even when turned to off, had one running outdoors & let it try for almost two hours, took a reading on the ESP determined it was bad, replaced and ran good as new.
Thanks Nitro-fish. Can I ask how you tested the ESP? With an ohmmeter? What are the values I should be seeing?
Harman ESP Test
Is there a way to check the ESP besides replacing it?? I assume it works on resistance. What happens if you jump the plug terminals?? Such as on P38+, 2 knob board..
