I had the same problem. I took the nozzle head off and blew through it with air. I also blew through the air line, this is the one that goes to motor. It has worked fine ever since.

try getting out a pair of channel lock pliers and squeeze the cap enough to grab the insert that is just spinning inside the cap...after you get it off, you may need to replace the cap with a new one

It seems as if you are not holding the igniter long enough after it fires, have you tried holding the igniter down for a few seconds more to allow the safety cut out to warm up, (Similar to the gas heaters, when ignited keep the flame going for the thermal coupling to heat up), If you do this and it still goes out the safety valve is faulty, but try holding it in longer before messing about with the coupling.

Check the fuel filter located on the end of suction tube. It requires some dismantling, best to have a manual on it.

Reddy... | Answered on Dec 05, 2011

You can refer to this manual: http://www.bealsmotor.com/Desa%20Hot%20Surface%20Manual.pdf
They have a detailed troubleshooting guide. You will need a multimeter and some electronic experience for some of the tests. I hope this helps!

The R110 is a spark plug heater, as you know. It does not have the sophisticated electronics that the newer heaters have.

My guess: SP heater runs 30 seconds & shuts down- bypassphotocell. If it runs fine, then the photocell is defective.The test is simpleIf the photocell proves to be good follow these troubleshooting tips

Just because there is fuel & spark does not necessarily mean there will be combustion. The fuel must be delivered at the correct pressure, the correct volume, and must be delivered as a fog- not a mist.

My suggestions:
  1. set the pump pressure
  2. be sure the fuel filter is clean
  3. be sure no air leaks or vacuum leaks
  4. Desa recommended annual replacement of the nozzle. They wear out. When was the last time yours was changed?
