Had a box fire in my Harman PP38+ last week....I have nothing working on my stove..no feed or blower...I am thinking it is the esp probe that was ruined from the fire.

Where is the best place for the best price on these parts?

I am hoping the circuit board wasnt damaged but I know the probe being damaged will cause the whole unit not to function.
This is a manual light stove....manufactured in JUne of 1997.

Thanks..

Harman parts are sold by Harman Dealers. You will need your serial number or the old ESP in order to get the correct one. If you can see the coloring of the wires, that will work also they're either red or black...
 
Just out of curiosity, what caused the box fire?
 
I turned the feed rate to turbo...never had a problem before...but using different brand of pellets...The pellets began to build up in the ash bin without being completely burned up...this filled the bin and it began to overflow and was up to the edge of the burn pot...by the time i noticed this happening the ash bin and rest of the inside of the stove was full of flames...I turned the feed all the way down then the stove just stopped running all together...cleaned the stove ( what a mess of black sooty crap stuck to the insides) and vent pipes but now the stove will not turn on at all..no feed or blower working.
I am thinking that the esp probe is shot..the flames were too much.
I am not sure what caused it...the exhaust blower was working fine and the stove was running great at speeds up to 4 and 5.
I usually use INSTANT HEAT PELLETS but since we moved I had to try a new brand.
 
Check your vacuum hose too. Seems alot of sucking problems lately. Good luck
 
Glad you caught it before the fire got out of control.Could have been alot worse.Hope its nothing major,I'm sure it was putting out some serious heat...As a P-38 owner I'II watch this thread...
 
No, the vacuum hose is very small and hooks to the vacuum switch that is a door safety, bin open, bad gaskets etc. If the vacuum switch is not closing the stove will not auger in pellets and keep everything shut down till it senses a vacuum on startup. Hot stove can melt it sometimes. May well be in your best interests to take to a competant dealer for a compleat inspection. You had a serious event and if not comfortable with the compleat workings of this stove please seek a pro. Hate to see a post of your home or what remains of it on the front page of some news rag that does not know their head from a hole in the ground. Best of luck
 
If I was in your shoes I would start from square one and ask for help in figuring out what went wrong and also how to get your stove fixed and back in operation. A ESP probe is just one of the many safety devices on your stove that could be shutting everything down.

You have snap discs on your stove that will stop everything once they are tripped. Just one needs to be tripped to shut the stove off. There is also the vac switch which has been mentioned along with a vac hose, which has to do with the stove feeding pellets.

I would also ask how comfortable and knowledgeable you are with working on your stove?

Pics might be a good first step in this process. If you ask for help I'm sure the Harman members will help you out. Just don't jump to conculsions and take things one step at a time.

On second thought because you have had a fire already it may be best to get a stove tech in to go over your stove unless you feel that you want to take on the responsibility.
 
I decided not to attempt the repair job on my Harman...dropped it off at a repair shop this morning...will let ya know what the damage is.
 
Once again, best of luck. When you get it back you will hopefully have a uneventfull few years and be able to sleep without any worries.
