The AC heater element is most likely open. Replace it and it will restore AC operation.

Hello, here is the manual: -

Also found this site with a list of parts for the fridge you mentioned

Hope this helps, good luck

It sounds like the electric heater is not working as you say it works on gas, so the expensive bit is OK.
An appliance engineer should be able to get the spares and fix it.

Check outlet for voltage ,only if you know how ! if good then cord is bad

right where the gas comes out there is an elect igniter do you see or here it clicking some times carbon buildup causes it to ground out inproperly sometimes the bracket gets rusty the bracket needs to be able to fire a spark directly twards the jet good luck

Thankyou for your assistance, but i found the solution with electrolux direct.
Hope to use your site again sometime.

Electrolux RM212,F, wont cool on gas but appears to be ok on electric.
The flame lights but can only feel a slight chill in the freezer box, and the flame does not seem to adjust with the control.
