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
