The perennial issue. 3 way fridge not working on gas!
RE:Hymer B574 2002 Electrolux Fridge RM6201L does not work on gas. Hopefully there will be someone out there with some words of wisdom. As brief as I can make it, this is the problem. On releasing the push-in knob the ignition light would reappear after first going out. Research suggested the most common problem was with the burner, burner assembly was replaced.
The burner lights and the thermocouple is correctly positioned. No Cure Thermocouple replaced no fix. Decided to remove fridge for full investigation, realised this was a daunting job so settled for withdrawing it 6in which allows access to most of the vitals. No gas supply at this stage. Thermocouple (x 3) tested, all produce approx.30mvolt when blow torch applied. I believe this to be in order, The situation now is that the burner lights but the ignition system continues even after heat application. My thinking is that the thermocouple output operates the gas valve and also causes the ignition to cease; however neither happens. So is it the gas valve that is faulty? There are two wires connected to the gas valve, I suspect that these signal, via the switch box, to the ignited to stop on the required output from the thermocouple. I have looked at the voltage on these terminals and they are exactly the same as the thermocouple output, ie. climb to 30mv on application of heat to the thermocouple. So when the thermocouple outputs 30mv why does the ignited not cease and why does the gas valve not operate?
Do I buy a new switch box? £63
Do I buy a new control valve? £200 ouch!
Do I call in an expert?
Any suggestions gratefully received.
