It consists of a heat sensor connected to a solenoid; when the sensor is not heated by the pilot flame, the solenoid closes the gas supply line. $12.99 $ 12. You did not specify what type of baseboard heater this is. Thus, the thermocouple will turn off the patio heater as it tricks the gas value in to thinking that the pilot light is out. Takes a couple tries to get the hang of starting it up. When a thermocouple fails, the pilot light won't stay lighted. If this doesn’t work, you can hold a match or lighter on to of the thermocouple.

If this circuit is broken at the center, the net open circuit voltage (the Seebeck voltage) is a function of the junction temperature and the composition of the two metals. Fax:+86-755-85279220. The small propane tanks come in a three pack. God forbid that OSH would keep in stock replacement thermocouples for their own patio heaters right? It is one with a threaded end, which THIS PRODUCT ON AMAZON DOES NOT HAVE. Q: Where do I purchase a propane tank? 7 Balloo Crescent Bangor, Co. Down BT19 7WP Northern Ireland.
