ACE hardware, Tractor Supply, H Depot or Lowez should have what you need. Bring the old one with you. You may have to purchase one a bit longer, just keep the extra coiled up out of the way.

SOURCE: I have a sterling overhead heater QVF-75.Pilot

It's called the blower activation switch. It turns the blower on, when the heater reaches the proper temperature. The Thermocouple has nothing what-so-ever to do with the blower. It's simply a safety device for when the pilot goes out for some reason, it stops the gas from reaching the pilot. In other words, it locks up the gas control valve.

Most of the time, a "Limit Switch" stops the heater form overheating by shutting it down. However , these Sterling Heaters can be a little strange at times and what I would consider a limit switch, could be something different for Sterling. Check you Owners Manual to see what Sterling means by Limit Switch.

Hope this helps you to further troubleshoot the problem.

Bought a sterling 75 c garage heater burner lights but then 24 v transformer burns out


I didn't find that model but did see a pretty standard wiring schematic for Sterling garage heaters in one installation manual. I'm sure they didn't change much. I did notice they use a 50va transformer, not 40 which is likely what is getting used now. Don't think that would fix it, just an idea. Put a 5 amp fuse inline on the red side of the secondary side of the transformer. This will protect it. I'm willing to bet the ignitor section on the low voltage common is wired wrong. Remove the tstat wires, buy a resettable fuse and install it first. Then get the fan running first. If there is a g terminal jump red to green. This is fan only, start simple, hope this helps

Loosen the thermocouple nut where it goes in the control valve. Re-tighten it only finger tight and with the appropriate wrench, turn it ONLY a 1/4 turn more.

If you have it to tight, it will not heat up and open the gas valve. Make sure not to cross thread it.
FYI: Gas control valves on this type of heater rarely go bad. Unless, the control knob is forced in an inappropriate way.
