I have a 2007 Monaco diplomat DP40SFT and my front furnace is not getting power to the red wire going into the reset switch. The back one works and I’m trying to follow the wire to find out why I don’t have power, but no luck. Does anyone have a wiring diagram or can anyone tell me where all the connectors are. Thank you

Check for House 12V DC Panel in overhead cabinet in bedroom
F13 should be for furnace/air conditioner 15A fuse

See pg 164

That fuse is good and it seems to run the back furnace also. When I pull it the back one goes off.

Hi ! Welcome to IRV2! We're sure glad you joined the gang!

Noticed you are kinda new on IRV2 and wanted to say hello. I would suspect a control board problem, but not being familiar with your rig I can't be much help! Have fun and keep her between the ditches!

Good luck, happy trails, and God bless!

Do you have a Fuse in F23?
That is suppose to be for 'other' furnace

Check on A/C Unit Control Box---
DC for furnace can be fed for there also

Yes that fuse is also good. I did see the two blue wire from the ac go to the furnace and they change to yellow and black and neither have 12 volts. I do hear a click when I turn the the furnace on in the ac unit.

The heat pump doesn’t come on either when I switch to heat pump

Be sure to use a test light or voltmeter when checking fuses. I had a connection on the back of my fuse panel that was not making a connection.

You can use a signal tracer if needed. This sends a signal down the wire and you can sniff it out.
