Yes, an electrical outlet shorted when a lamp was plugged into it. It blew the breaker. I had no idea it was tied into the furnace line
yes the electrical socket works after resetting the circuit breaker.
I looked on the outside switch of the furnace for a fuse but there is no opening into the switch box. It is a regular metal electrical box with a on/off switch, no room for a fuse. and it is turned to on position.
the furnace is a Trane XE90 propane converted to natural gas.
I did not find any L1 or L2 located anywhere on the controls. but, when I checked the safety switch it has 120vac when it is pushed in.
Hello Robert, I still haven't located the fuse. I will keep searching today. I have a weak internet connection and lost it completely last night. I did find that there is voltage into the transformer but none out. A schematic of the pc bd would be nice, especially since I have no idea about auto fuses and what they look like. The fuses in my car are a 2 prong plug in and color coded for different amperages. My experience with electronics is welding equipment repairs. Okay, I will let you know when I find the fuse and if it is good or not.
by the way! I appreciate you walking me through this. I lost my job in September and really cannot afford a HVAC repair tech right now.
