Feeling the Heat

I walked into my house while ago to a 77-78 degree inside and 62 or so outside and the stove was still burning away. i have it set around 75 degrees on room temp auto. My probe is extended and is 10 feet away from the stove. I touched the probe and the status light status light stayed on and turned it to 50 and it continued to stay on and feed pellets. I even tried a hair dryer and it gave me a 4 blink stated a failed probe. But after a few blinks it cleared up. But it continued to feed and status light stayed on. One thing is that the convection blower and light does go out. Any thoughts?
 
how long did you leave it at 50F ? it takes time to shut down. overshooting by 2 degrees is certainly no case for alarm. make sure that the ignition switch is still in "auto" or it wont shut off.

I left it bout 5 minutes at 50F....well since i've owned it (bought it used) it has never shut off on room temp auto. I have it 10 feet away and 3 feet high and taped on a back of a leather chair
 
If you do not have OAK just leave it behind the stove. Sorry just read you have direct vent, can you send photo's?

I have an OAK....
 
Probes rarely go bad, but is the first item to look at, in cleaning out the exhaust could have gotten comprimised. Can you send photo's of the unit?

This probe was lying on the floor of the home i bought it from. So someone could have stepped on it or anything....i clean my exhaust at every cleaning w/ pulling of the esp probe....so that being compromised not sure because i'm very careful...
 
Check the contacts behind the stove, make sure they are tight
 
I had the wires break from one of the crimps on my contacts and it made my stove do some haywire stuff like that, you may have a broken connection back there.
 
I threw my probe in the trash the first day I had the stove.

Check the landfills in NJ.
 
This morning before I left for work I turned it to 50F for bout 15 minutes and it never went off. The convection did turn off as well as the convection light. So I turned it off and then to back on and the status light came back on and the stove kept feeding. I suspect a probe but for $16.00 is a good start for troubleshooting...,
 
it takes an average of 45 minutes to shut down completely

I understand that.. Mine is average of 90 minutes.... But it's not going into shut down... The status light is staying on so the stove is still calling for heat
 
certainly could be the probe then, and that's a relatively cheap thing to swap. 90 minutes is a long time. Stove seem to run ok in Stove Temp mode?

90 minutes to me is a long time .... But it being all cast it takes a while to cool off for the ESP to read the temp to shut off the combustion motor... Stove temp mode to me works pretty good...what ever setting I put it on it responds quickly and begins feeding and increases the fire as necessary
