dometic RM 1350 ventilations fans only work on gas

[Geneandea]

The fridge is in a slide, My condenser cooling fans won't run when the fridge is on electric. I have replaced the two electric heating elements thinking it wasn't getting hot enough. But it didn't help. Fridge works good until upper 80s and 90s. As soon as I switched to gas mode the fans come on. My question can the limit switch (sensor) on the the condenser fins not work correctly at the lower range but ok for gas which is hotter.
Thanks Gene

There is a thermostat that controls the fans. It's probable that it gets hotter in the compartment on gas, and it appears maybe your thermostat may be defective.

I use an Emerson 3F05-1 which is adjustable if you need to replace yours.

Exterior fans are controlled by Condenser FIN Temp regardless of heat source

Electric and gas should transfer roughly the same temp......325*F/350*F

Exterior Fans thermostat is attached to Condenser FIN
Thermostat closes starting fans when Condenser FIN temp reaches 149*F +/- 9* and opens stopping fans when Condenser FIN temp drops to 122*F +/-9*

Condenser FIN Temp is dependent on amount of Ammonia Liquid BOILED into Hot Ammonia Vapor and Draft/airflow across Condenser FINs

Does the freezer/fridge cool/maintain correct temps when using the AC Elements?
YES...then all is OK
NO....then issue is Elements are not generating sufficient heat to boil enough ammonia (Low AC Voltage, Loose Element Leads connections, Element holders etc)
