RM7401 / EBL 269 problem

[Pilote87]

Hi Gals and Guys,

I have a problem with the non functioning of my fridge. I have removed the cooker hob so I can access the top of the fridge and have checked the voltage at the 12 volt terminals. Strangely, I am seeing different voltages depending on which energy function I select, but they are all below 6.2 volts. I haven't, as yet, checked the voltages with the engine running. On the overhead panel I have a reading of over 13 volts, believable because the sun is still on the solar panel. The engine battery is showing 12.7 volts, although probably irrelevant.

Any ideas, please?

What’s wrong with the fridge?

What’s wrong with the fridge?

It doesn't operate on any of the energy sources. The light which indicates the fuel selected is very dim in all three positions - not surprising if there is only half the required voltage.

have you checked the power module 12v supply ground connection.(I believe that the burner control and gas valve operate at 1.5 v via the power module)
If you need it , there is an operation manual (including a wiring diagram) for The Dometic 7 series fridge on page 4 of Manuals for Motorhome Stuff that is in Resources (found in the menu)
