2015 Thor Ace ... Ac and water heater out ?

[Gfamily]

Hello rv brothers and sisters,

My Ac , water heater and tank led levels gauges are not working. Checked fuses and breakers and all are good. Anyone have an idea where else I should check to fix the issues?

If you haven't already, check for power after the fuses and breakers with a meter.

If theses problems showed up after setting for the winter they may not all have the same cause. Example, the water heater element may have been energized with no water in the tank and a critter may have made a home in your rooftop AC.

Does your water heater not work on either gas or electric?

Does the AC and gauges not work on generator, plugged in, battery?

I don’t winterize the rig I store it in my rv garage. The water heater does not work in both electric and gas .

The ac was working just fine but, when we took off from the last stop I went to check the water level gauges and noticed the led bar dimmed and went out.

The ac and gauges doesn’t work on gen, shore power or battery ... the only gauges that do work on the panel are the water pump , slides and gen start

Reads more like a 12VDC problem and not a 120VAC. DC is the controlling power for all three and all three could be on the same fuse.

No idea which fuse. A good place to start would be to establish an account at - https://www.thormotorcoach.com/owner-resource/ and see what Thor has made available for your coach. Here's an example for a 2018 Hurricane 35M.

It does look like 12 volt issue. Hopefully one problem causing all three issues.I don't know of any likely fuse locations other than the main panel under the bed (in my case 2015 ACE 29.3).

Sweetbriar's info source looks helpful, I plan to set up an account when I return from today's excursion.

How is your battery voltage doing? If they are the original batteries, may be getting weak. Although this should not be an issue when plugged in or on generator if the converter is operating properly.

Hi neighbor. Is it possible to pull the panel and look for loose or bad connections?

I’ve check the fuse box under the bed and all fuse and breakers seem to be fine getting 120 to the all breakers and no blown fuses.

the house battery’s and chassis battery’s are fine ... just replaced the chassis a few days ago and the house battery’s are running good.

I could do that haven’t checked for lose connections.

Nothing loose and doesn’t seem to be any bad connections

Trying to find out if there would be any other fuse or relay that might controlling these issues anyone know what these are

Look like high current DC relays. The two in my somewhat older Hurricane are interlocks for the slides. The parking brake closes the relay and allows slide motion.

Just checked the furnace and that’s out too. So now it’s the furnace , AC , water heater (both electric and Gas) and tank level monitors ... hmmmm

[Sweetbriar]

Furnace is 12VDC powered and controlled. It is also the 12VDC power source for the thermostat which controls when the A/C comes on. Is you fridge a propane type? If so good possibility it's also on vacation.

If the 50A breaker, battery compartment, is tripped you'd have zero DC voltage available from the batteries. If it's not tripped or your on shore power I'd inspect the converter fuses, probably 30A or 35A, located on the front or rear. My fuses, WF9800, are on the front.
