Dometic RM 2852 keeps sparking ignitor

The ignitor keeps sparking and burner is light with Blue Flame. The thermocouple does not have any millivolt reading (flame one) and when I pulled both connections from the main board I measured 43 ohm and this did not change when running on gas (flame on) The DC voltage measures 13.62 at the connection. Gas solenoid operates, I have cleaned the igniator, burener assemble, the thermocouple. I would ecpect the thermocouple to change resistance when the burner is running. Works fine on AC power.

Thoughts on what else to try.

Thanks in advance.

I had a different model than yours and it sparked all the time. Being a retired fire investigator it really spooked me. I replaced the fridge with a 10 cu. ft. electric one and I love it. It freezes the ice trays quickly and keeps a better temp than the old one. I also have had wireless thermometers in both the freezer and fridge compartments of the old and new one. I hope that you get it worked out.
