It is a Dometic model 2803 probably original in 1990. The local AS dealer says it is way past lifetime most parts are really expensive. New ones he said last about 5 to 10 years. Anybody got any suggestions as to a low cost quick fix.
Is it time to replace? If so, what should I put in?
Attached is a picture of the flame. Does it look normal?
Thanks for looking,
OK, I have replaced the thermocouple and put in a new board. Thanks Andy for the part number. It still does the same thing. It lights and gets a great flame. It keeps sparking for about 3 minutes and then shuts down, flame goes out. Now up to about $190 with the thermocouple and board.
