Electric basement heater

[bj400a]

I have a 2005 Dolphin that has a basement type heater and air conditioner.
When I turn heater on and set thermostat at a temp. the heater will run for about 15 minutes them trip a circuit switch of 15 volt. This also happens when I switch over to propane heater. Air conditioner works all day long. Switched out thermostat and problem continues. Took RV to local RV repair shop. They said they found a mouse nest in tubing but problem persisted. Anyone know a shop in Washington Oregon area that works on these types of furnace?

Do you have one or two propane furnaces? I believe your 15 volt breaker is actually a 15 Amp. AC breaker.

The units National RV used a really residential units, try techs that service household units.

Try running on 30 amp, does it run run on Gennerator?

The HVAC is a Coleman/Mac unit:

I'd find an authorized support center to work on it.

When basement ac selected and temp more than degrees different it will switch to the gas furnace, so your problem could be with just the gas furnace.
