Had a 50 degree temp drop this weekend so we from using the a/c to wanting to use the heat. However the furnace wouldn't light. Not sure why.. But here's what I experienced.
Connected to 30AMP service:
Moved the a/c , off, heat switch from off to heat. Heard a click at the a/c then the furnace blower ran, but no ignite. I cycled this a couple times with no luck in getting the furnance to blow heat. Told kids to put on a sweat shirt and go outside.
Pull the Dometic thermostat cover and checked all the connection all appeared secured.
Came home, tried again without 30 amp service, pulling off the battery.
No click at the A/C, but furnace lite right up blowing heat.
Plugged in to house power using 30amp to 110 / 20amp reducer, heard click at a/c but furnace fired right up.
Do you guys hear a click at the a/c? Any thoughts on why no ignite originally?
