Furnace and lights out!

Hoping to get some help figuring out how to fix this issue.
Heres whats going on..
Went to kick the furnace on and all the lights went out...with the exception of the bathroom lights. Furnace and lights are not coming on. All the outlets still work. Think power was overloaded? Flipped the breaker but did not fix. Is there a fuse that may have blown? Is there a GFI reset button I am not seeing that may help? Help its really cold haha

Your lights and furnace fan should run off 12V. Sounds like a blown 12V fuse but don't ask me where the fuses are.

I did find some fuses in the back closet area. Is is pretty obvious if I pull them off that one has been blown?

Yes.. hopefully they are 'labeled' properly.. check that one... sometimes older fuses will fail. DC circuit may be weak..

-Check for proper voltage... if voltage low, check that and resolve if not correct. (+12.5VDC).. it is possible the battery (12VDC) supply has a problem...

Try ONE more fuse... PROPER value!! do not 'increase' the size!!!!

If it fails, you have a wiring / furnace part failure. In my experiences, the highest 'load' is from the 'fan motor'... Check that it is 'free' spinning... bugs or vermin can get in there and nest in the fan blades... the 'start' load could 'blow' the fuse (the fuse is there to protect.. right?)

Here is a possible sequence...
- Shut off furnace..try unplugging all of the wires going to the furnace AND all parts inside the furnace (fan and solenoid).. Ensure the power wires are secure on the fuse panel... then replace the fuse.
.... If fuse blows, your problem is likely somewhere in the wiring.. most likely where the wires enter the furnace...
.... another possibility is that wires inside were chomped on by something...

- Hopefully the fuse will not blow. If it doesn't, turn on the Furnace control (thermostat)
.... fuse blows? disconnect the thermostat and check for 'short' to ground

- If thermostat and wiring appear to be OK...
.... remove fuse, turn off thermostat, plug in the 'control board'... install the fuse and turn on the thermostat.
.... If fuse blows, problem may be in the 'control' board of the furnace (shorted, damaged).. if so, replace the board.. recheck..

- If fuse doesn't blow... check for damaged/shorted parts in the furnace... motor, gas valve solenoid....

Let us know how you do..
Peace and Blessings..

Check your converter. We had this same thing happen one (cold) night last year coming back from AlumaFiesta. Everything was just fine in Tucson but we noticed that our interior lights were dimming down the first night on our way home in Silver City. Didn't really think about it and we were not using the furnace. Next night in northern NM we did need the furnace and after about an hour or so the lights were very dim and the furnace was no longer running. It did get cold (about 20 F) that night but we were able to make it to morning and get headed home. Our mechanic found the problem right away - the converter had failed which meant that the battery was not charging when connected to shore power. A few days and a few bucks later the problem was fixed. So - if the lights slowly dimmed this could be the problem, if however they were on one minute and out the next then there is likely a fuse that blew. My AS has fuses front, back, and in the middle. Check your owner's manual because there could be multiple fuse boxes.
