Heaters out!!....need help

[Donnette413]

Both the gas and electric forward heaters, the electric fireplace and electric water heater are all out. Thank God for the gas water heater and rear gas heat.
Any suggestion? Not the GFCI and breakers don't appear to be tripped.

What is the battery voltage?

The electric fireplace and water heater, will only work on either shorepower or generator. If those aren't working while you are on shorepower, then either your shorepower is out, your transfer switch isn't working correctly, or you have tripped your main circuit breaker which is in the hallway. You can try shifting over to generator mode and see if that solves the problem. If it does, then you know it's a shorepower or transfer switch problem.

You can verify whether you have 120vac (non inverter) power, by plugging something into one of the sockets on the drivers side behind the sofa. Those sockets are not on the inverter, they are only on the 120vac shorepower or generator. Same thing with the two 120v sockets on the drivers side bedroom.

Assuming you aren't getting power to those devices, then it means you also are not getting power to your Magnum converter either, so your house batteries could have discharged to the point where the 12v controls for your furnace thermostats will stop working at some point when the batteries get too low.

What does your house battery voltage indicate, as it shows on the Magnum controller (above the drivers head cabinet on PS)? What status does that controller show ? (charging in float mode, or I suspect inverting).

I just re-read your original post. What do you mean by "Electric forward heaters"? Is this a space heater (or two) you plugged in, and if so, exactly which plug did you plug it into? (behind the sofa, on the front center floor by driver, on the floor by passenger seat, or under dining table?)

Can you verify whether your refrig inside light is on when you open the door. If you plugged electrical heaters into an inverter socket, with the additional load of the refrig and mwave you could have tripped the 30 amp breaker on the inverter down in the basement storage. Go into the storage bay on driver side and look up to find the white box. There is a pushbutton 30 amp fuse on the side of it). This wouldn't account for the fireplace and water heater not working, but you may have a couple problems going on here.

what would the battery voltage have to do with the electric fireplace, electric water heater?

Have you checked your circuit breakers?

Best of luck,

12V is used to control a number of things in the coach and power some of the appliances (like the furnace). Troubleshooting power problems involves both the 120 VAC and well as the 12 VDC side of things.

If the battery voltage is to low, the inverter will quit. When the heater is on and the fireplace is on the demand for current is high and could be to high to keep the inverter operating. It will automatically shut down to protect itself.

OP has failed to come back and either answer any questions or ask for additional help........so appears that the problem is resolved.

I think you are right.

I dont think to many coaches that have electric fireplaces and HW heaters have them set up to run off the inverter. Maybe some of the higher end coaches with 16 batteries and two 3000 watt inverters. I know my higher draw electric appliances have direct circuits fed from the electric panel except the refrigerator

Icepick,

What the previous poster wrote does not imply that those appliances run off of inverter power. If AC voltage to the coach is marginal, the high current draw of the hot water heater and the electric fireplace and reduce voltage to the point that the inverter/charger will shut off to protect itself. Similar self protective action in the charger section if the house batteries are too low to be charged with the current provided by the charger.

Your refrigerator breaker is on a subpanel for inverter powered equipment. This is normally located in your main breaker box as well unless this was added after Tiffin built the coach.

Thanks a lot!!
