heater serial # 3687823 was working fine then just stopped. cant get it to light now


if the pilot lights when held but wont stay lit, the thermocouple is shot, local hardware stores sell universal thermocouples. self explanatory to replace. if even when pressing the button the pilot doesn't light there is a blockage in the gas line or control valve. that needs a pro to fix.

pilot assembly parts or thermocouples


Hardware store thermocouples don't work on patio heaters. The fittings are not the same thread and they are not set up for the anti tilt safety switch. You'll need to purchase the parts from Blue Rhino.

I want to know where to buy a thermo coupler for an All Pro SPC 150.


Thermocouples can be purchased at most hardware stores, home depot, etc. The only difference for a thermocouple is the length. There are heavy duty types and regular. I would suggest using a heavy duty thermocouple. Also, it is recommened that thermocouples be changed every 2-3 years to prevent unnecessary failures, which usually occur when you need the unit the most.

I am looking for a thermocouple for a Charmglow Pure Comfort Solution - Model #CG07010491


Thermocouples are kind of generic. If you remove the one on the heater, you can take it to your local hardware store and match it up. The new ones usually come with adapters for the three main ways they attach. The only thing you really need to make sure of is that is the right length.
