Norcold 982 A7 when on LP GAS

yes works fine on A/C, we determined that I am not getting 12volts at the control board while the fridge is in use. my guess is that somewhere along the frame a mouse ate a part of the wire. But i cannot find where the wire goes to.

Are you saying it works fine on electric power? And has and issue on propane? Sorry I skimmed over it quick.

Trust me. The 12 volt fuse/CB is there. May not be correctly labeled, but it is there. Doug

Actually all the writing is crystal clear in that compartment, nothing is showing refer or fridge, all fuses are labeled.

Usually Monaco/HR, used the Left front outside storage for the large Circuit 12 volt panel and refer 12 volt power. They also used a 12 volt circuit breaker(5 amp) instead of a 12 volt ATC fuse for the refer 12 volt circuit. Unless after 25 years your printed label for ALL the circuits is gone, the schematic will tell you what circuits are there and their place on the large circuit fuse panel. Doug

Common causes of voltage drop in a 12 volt circuit when load is applied

1. LOOSE spades holding a ATC fuse
2. Loose nuts when on a 12 volt Circuit Breaker
3. BAD ATC fuse that the tungston has not fully blown and separated.

Update:
I used a 12v battery from my truck and hooked it up to the RV fridge and it worked perfectly in LP/GAS mode.
I again verified that I have 13.95 volts between the power and ground at the RV board, I then turned on the fridge and watched the voltage on the voltage meter and the power voltage went do to 7volts, while the fridge was sparking up... and then it through the A7. I ran a separate ground cable to the ground and no change.
I then ran the wire direct from the house battery to the fridge and the fridge works. I cannot find the fuse in either of my 3 fuse panels for the fridge. I even tried to short the positive and negative wires feeding the fridge and it didn't even have a spark let alone blow a fuse. Can anyone help with where the other end of this positive wire goes to? Which fuse box?

The "reset" procedure is for a NO CO lockout. NOTHING else. Your refer will operate to 10.5 volts dc. The voltage is taken at the Pos and Neg input wires to the refer from the RV. NO OTHER testing is needed. Now, when you get an A7 and the voltage IS over 12.0 volts, you then connect a 12 volt battery source, bypassing the RV Power Converter OR Inverter/Charger if you have one. Turn them off or disconnect the 120 shore Power. Best way is to use a 12 volt battery from a UPS system or a 12 volt battery from a 12 volt Power tool. Doug

Your voltages are good. Remove check and clean all board connectors. Search for a Utube troubleshooting video.
