I need a thermocoupler for a model 250A propane space heater. Where can I get it? The heater was working fine and now it only works at about 20% capacity

The manual is here:
http://www.desatech.com/manuals/Construction%20Heaters/000122-01.pdf

The 13" thermocouple with junction box is PN 6654 or PN 113884-01 (Same exact one)

Yes, I do. Master Distributors stocks parts for All Pro heaters. http://www.masterparts.net/

you should clean the thermocoupler if it need to be replace the new one will be in a kit so you will need no etra parts

This sounds like a problem with your thermocouple.

Just remove the end of the thermocouple from where is goes into the gas valve and leave the end that goes into the flame in place.

Clean the end of the thermocouple connect by scraping off just a little metal from the end just about there the nut tightens the thermocouple into the gas valve. After you have exposed some new metal do the same inside the valve where the thermocouple seats into the gas valve.
Use a small pic or similar item to scrape inside the gas valve to expose some new metal there also.

Now reassemble the thermocouple into the gas valve and see if the heater works.

Here is a link with some more instructions.

If this does not solve the problem you may need a new thermocouple and you can find that at www.desaparts.com

Replace the thermocoupler?

I have a Charmglow Patio Heater Model SRPH02, it needed a Thermocouple and searching the net was hard to find an ariginal part, but here it is, call 1-866-814-0585 $3.95 +6.00 shipping the original part.

Problem is either the thermocouple or the thermoelectric valve. I have one of these as well with the same problem. On mine it is not the thermocouple. I have replaced the thermocoupler and still have the problem. A thermoelectric valve is $42.25 at http://www.masterheaters.com/propane/
Im looking for a cheaper part. Any suggestions?

If you have a pilot, you have a thermocouple. I would start with the thermocouple. The thermocouple is supposed to be heated by the piolet and to keep the pilot gas on. If it is faulty, the pilot will quit and the heater will not reignite until you light it again. Good luck...Lee

almost all thermocouples are universal just need to know the length, ie. 18" , 20", 24" etc...

When holding button in,you are overiding themocouple funtion. You probably need to replace the thermocouple
