Question about Dometic Refrigerators
Hi and welcome to FixYa. I am Kelly.
Sounds like you have one of "those" problems with the energy management light.
If you don't already have it the Dometic "first generation" service manual can be found here: http://bryantrv.com/docs2/docs/AES.pdf (roughly 2.14 mb / 94 pages)
This almost sounds like there is less than 11 VDC to the control panel and it is switching to the 25 min delay mode.
(OR someone has run a different power wire to the unit bypassing the ignition switch.) <-pure speculation.
As with the first and second generation series
A.E.S. models, any time the battery voltage to
the terminal block drops to approximately 9.5
volts DC, the refrigerator will switch to a
nonthermostatically regulated gas flame to
insure the unit will still provide cooling for
As a low battery indication, the green mode switch indicator lamp will shut completely off during the voltage drop.
The refrigerator must be connected
directly to the house battery with 2 wires of
adequate capacity to avoid a voltage drop.
There could be a temp short of the door switch to the chassis that is shorting only as the door is closed. (seen this one before)
Have you tried reading just resistance on the light switch wires to the chassis as you open and close the door?
Note that pages 64 - 66 have some very pertinent data about resistance readings.
There is a service bulletin #46 out on this unit that I do not have.
Although unrelated to this problem take a look at these manuals. They are a virtual "on line" pot of gold for RV repair people. http://bryantrv.com/docs.html
Thanks for Choosing FixYa.

Sounds to me that the compressor start capacitor is the first thing I would check. You will need to get on the top of your camper and remove the outer cover. The capacitor is the part that stores up enough energy to kick start the compressor when it starts. Sometimes a capacitor will swell if bad, but not always. Mark your wiring before removal and have someone test the capacitor to see if it needs replaced. I will be here should you have any questions. If helpful please rate this solution, Thanks Sea Breeze
