Dometic Stove problem

[43oswegatchie]

I have an issue with a common stovetop 2 burner Dometic stove. It is a model # 2BR-1066050. One burner works fine, the other one does not stay lit after holding the knob in for 10-20 seconds as recommended. It is a manual ignite and it is getting ample propane. Anyone else had this issue and how did you fix it? Thanks, Scott

The stove has a special shut off safety feature that may be involved in your situation. So talk to the experts about it in case you need a specific replacement part. Perhaps they will send you a model specific trouble shooting guide list by email.

From the sound of the symptoms, it has a temperature sensor (thermocouple) that when hot keeps the gas flowing. If the flame goes out, it stops the gas flowing. It is a safety feature. Could be misaligned or defective. Look at both burners and note any differences.

I called Dometic first, and they told me they honestly could not trouble shoot it for me. Recommended a service professional. By the time I pay for that, I may as well buy a new stove. I am trying to see what is on Youtube or other forums such as RVnet.

If I put something against the knob, it will stay on. It is only when I release it that it goes out. Does that sound like it could still be the thermocouple? I will take a look and see if maybe it became loose or disconnected too. Thanks for the reply!

If it is doing that then it sounds like the issue is in the control unit that is right behind the knob. Sometimes a good cleaning works wonders. But it could be a worn out part in that unit. Over time wear and tear happens to parts that move.

I did find a spare parts diagram for you. There is an alternate model number for that stove that ends in 49 instead of 50. The maker of the stove is "Cramer", the seller, ie distributor is Dometic.

Here is the link to the parts diagram from a website in Australia. Dometic USA does not have the spare parts diagram posted.

Bad thermocouple is a good place to start looking! Could be dirty, but likely needs to be replaced. Shouldn’t be very hard to do or very expensive to buy!

Taking off the old one for a supply house to match works unless you can get good pictures of the part and the ID tag on the stove.

Pushing in on the knob overrides the thermocouple or there would be no way to light it.  You have to hold the knob in until the thermocouple gets hot enough to hold the valve open.  Look at the one that works, it should have a little metal piece sticking in the flame.  The other one should be just like it.  Thermocouples do go bad.  They can be tested (disconnected first) with an Ohm meter.

Thanks for finding that. Dometic certainly does not make it easy to find info in the US, even though the stoves are fairly common here. Seems likely it is a thermocouple, but to get at it the whole stove has to be removed. Uggg! And the only way to really to make sure it is would be to remove the thermo from the other burner and try it on the non-working burner. Double the work.

$90 and it is on the diagram posted above. Very helpful! Thanks!

Thanks Brian. They do stick up into the burner. I tried cleaning and brushing it, but still no help. Do you have to disconnect the whole thing or just one side of it (and if so, which side, the knob or the burner?). Thanks again!

The thermocouple has two wires.  One of the wires has to be disconnected to read with an Ohm meter using both wires.  Test both thermocouples to get a comparison.  You may be able to find a thermocouple locally but it would have to have nearly the same Ohm reading as the good one.
