Combi mast dead air conditioner dead microwave dead - fix

[SkydiverRox]

While boon-docking, our air conditioner would not come on. Also, microwave power was dead.

Our Combi Master display monitor was black screen dead and we did not have access to shore power to plug in which would have fixed the problem.

We fixed our problem by lifting the seat over the bed to get to the lithium battery and flip a switch, which is located on the battery, turned it off and then back on.

Note: if the display for the SOC (State Of Charge) drops to 0%, the Combi Master display goes black screen. We have been running the rv engine to have air conditioning at night. In cooler climates, the kitchen vent fan was used and we did not have to run the engine or drive to charge the battery as long as the SOC was over 20-30%, we could make it through the night without waking to a dead rv.

(If I’ve worded this wrong, please correct it.)
Hope this helps someone.

Their info page says it is a 2023 Sequence which I looked up and seems to be a camping van. It would appear it is brand new and their could be a lot of bugs not yet worked out. It may not have a generator and the owners could be new to RVing with zero experience.

Sounds as though it was run dead and not recharged. Solar? Inverter breaker tripped? I’m not familiar with.

Are you sure it was on the Battery or was it on the Inverter ? The Inverter has a switch for "Charge only " or "on " .

Do you have the 200AH system or the 400AH ?

Do you have the "Battery Safety Relay ( BSR ) ? Its yellow & has a flip type switch & has to have the Center Button depressed when reseting ?

You can go to the Thor owners sight & get a lot of info on you RV , including wiring Schematic's.
