Heater click and flickering

Last night we were sitting in our Lacrosse and plugged into our 50amp at home. Lights and AC on with no problem. We then heard a clicking noise coming from the furnace under the pantry and the lights were flickering with the clicking noise.

Checked fuses and breakers. All appeared normal. I finally flipped the 50amp breaker off then back on. Clicking and flickering stopped.

Three hours later it started again. Tried flipping breaker and it stopped for a few seconds. Decided to unplug all power until I can do some research.

Fyi. It's been raining for a week with no problems till now.

Video attached.

Any ideas?

Should the furnace have been trying to light?

Even if the propane isn't on, if the thermostat called for it to light it would try to ignite until it locked itself out due to no flame sensed.

Heater clicking

We just bought our 2017 Lacrosse 1 week ago and are having the exact
same problem with the heater clicking when plugged in with nothing on?
What was your solution to this problem? Thanks for any help....

Dumb question perhaps - is your thermostat set to auto? If so, it will call for heat below the set temp and AC above the temp. If the propane is off and it calls for heat, it will try to ignite three times and then go into lockout mode.

Bought new prime time camper second time out furnace made same noises had them come out and it was a circuit board. They said on horizontal mounted furnaces they get moisture on the mounting plate that the electronics mount to.

On certain models of Atwood furnaces water gets on the control board. There is a kit that remounts the board and some seals that prevents this. The kit is free for the first 2 years
