|Re: Dometic Fridge problems by Elijahs1976CoachmenCabover|
|Got a little problem here.. Fridge Defrosted, All the food went bad..
Okay this is going to be a long one because I did some diagnostics I want to run through as well.. Let me explain the problem first though..
this is a very old model that was working fine until just a few weeks ago..
In fact the freezer was so cold that I had decided to chip the ice out of it because it was taking up my freezer space and I couldn't fit anything in it.. After doing that I kept it running.. BTW I live in this Camper, so the fridge is on all the time..
Anyway.. The fridge defrosted and I tried the knobs, nothing works, I put it on 110AC nothing happens, I put it on 12V ad all that happens is it dims the cabin 12V lighting a little bit, But I am afraid to put it in LP mode because it is so old I don't want to start a fire, Plus I have a limited amount of Gas and money..
Earlier today I went out with my multimeter and tested some circuits..
I tested Continuity on the Thermostat, Tested Voltage Coming in at 109.8 Volts AC, Tested 12V without load at 14.6Volts DC, With load came down to 13.9 Volts DC.. Tested Power to the Heater on AC and DC sides with the selector Knob set to each, and got Voltage.. I do not smell Freon, or ammonia at all.. I know the coil looks a bit rusty, but it seems fine.. I am starting to suspect that the Heaters are either burned out or the Thermostat may be going out.. in other words. if the fridge is HOT inside the thermostat will kick on, but if it gets even slightly cool it will kick off.. Or somewhere I have a bad switch/loose connection.. I need help on this because I really need my fridge working so I can get Groceries again.. I am tired of Canned food after a week.. I am about to go get a Dorm Fridge or something.. This is ridiculous.. Could I have Damaged something when I was CHiseling out the Ice from the Freezer? or Could I maybe have a bad Switch.. I don't know.. All I know is that it is set to MAX AC and it is over 100 Degrees outside.. It is also over 100 Degrees in the Refrigerator.. Please help if you know anything that can help me.. Write me back.. Thank you so very much!!
I repeat.. Power 110 Volts to one heater 1 (top) only on AC mode
Power 13.8 Volts to heater 2 (bottom) (in 12 Volt Mode Only)
12 Volt dims the Cabin 12 V lights slightly, but does not seem sufficient to cool the fridge..
My Converter is running with no load at 14.6 Volts AC and it is capable of 20 AMPERES..
