I have a Smev range in my truck camper. It uses piezo spark ignition for the burners and oven. I'm having a problem now with the oven staying lit. It lights fine when holding the knob in but goes out as soon as I release it. I just tried installing a new thermocouple but the problem remains. Any ideas? Thanks, Steve

That is the condition of a bad thermocouple. It is not unheard of to have a new one that does not work as well

Can it be tested? Throwing parts at it is a little inconvenient. The stove is made in Sweden and Dometic has recently purchased this brand but so far is not importing parts. I had to go to the UK for a thermocouple...

If the thermocouple reads 13mv or higher it should be good.Using a meter set on mv you put one lead on the end and one on the side.This reading has to be done when the thermocouple is in a flame.

SMEV was bought out by Dometic. I searched the Dometic website, and found the owners manual. Reading through it, you might want to try the manual lighting method to see if it will work.

Thanks, SteveI know this sounds simple, so please know I mean no offense. When you hold the knob in and light it, do you continue to hold it in for a short while....maybe 15-20 seconds??? If you release the knob at the very second it lights, it will almost always go out.Just a thought...Christian
