Dometic RM2193\r\nWorks on 120V, but not on gaz.

These fridges require that the control switches be in the correct position for the power source you want to use. If you try to operate the fridge on gas and have the electric 120V-AC switch on, all you'll get is the gas pilot light to stay lit. Also, when running on gas, the electric has to be off.

Here's a link to the manual for your unit. Print a copy and save an electronic one for future use, in case you lose your printout.

Hope having the manual helps you to get the fridge working on all the power sources you need! Best regards!

Try drilling out the jet one size or check gas pressure
