Hey Gang, woke up this morning (0430) to a humming/vibrating sound by the propane tank (street side), and a 45 degree trailer. Went out and switched tanks on regulator and sound went away. Tried to start the furnace. The blower comes on for 10-15 seconds, and then shuts off. Stove works, fridge works, hot water tank works!! Voltage is good, and I ran the generator just to make sure (boondocking here). Not hearing a spark on the furnace at all. Any ideas besides sail switch or mother board??
And does the outside panel just pull off after taking screws out?? Seems to be hung up on the exhaust tubes and I don’t want to force it unless that’s the only way. THANK YOU!!

Signed- Why is it so damn cold in Arizona!!
