Furnace fan won’t quit running

[[email protected]]

My furnace fan in my 2950 RL runs even when thermostat is in off position, noticed it was draining my battery while towing, any ideas?

I'm suprised no one has any ideas for you. Can anyone offer up suggestions ??

Without knowing details of your rig and thermostat - what I've seen in the past is a short in the wires to the furnace - normally right at the furnace where the wires enter the metal shroud. Again depending upon your specifics it could also be a the board not shutting off the fan - this is doubtful. Try puling the 12VDC fuse and then replacing it and see if the furnace fan starts right back up (with the thermostat in the off position). If it does not after doing this, then cycle the furnace (operate it it with heat) and then see if it shuts off after the cycle.

Forgot to ask - is the furnace really operating or is it just the fan? If the furnace is operating and heating - may be the thermostat.

We just returned after Five days and I noticed the same thing in our Imagine XLS 22MLE. I turned Fan on Auto, and then Off, but it continues to run. Plugged into shore power at home (30 Amp).

Okay, maybe not the Furnace Blower, this is coming from the square electronic panel below the Pantry that has the AC’s Main Breaker and fuses, this fan continues without stopping. ��

Pulled the 30 Amp shore power plug and it stopped, but when I plugged the power back in, the fan started running again. 🤷🏼

Is it normal for it to run like this? We were only 47 miles away.

Sounds like it is the fan for the converter which provides 12 volts DC and charges your battery

I’m trying to find out if it is normal operation for the Power Converter breakers and fuses panel fan to continuously run, or will it eventually turn-off at some point? I unplugged the shore power and used my Lippert Connect app to check my batteries charge, it read 12.9V. Plugged in, the app reads 13.5V. 2 x 12V Deep Cycle Lead Acid batteries connected in parallel. It is late so I left it be for overnight.
