Question

-My truma heater on electric side has stopped working. It was ok for a bit on low setting then I turned it to next setting and it stopped after a bit. Checked all fuses, they are ok. Now it just blows cold air.

Answer

This could be a number of things, if it does not work on 2kw setting it is unlikely to be a problem with the heating elements as both elements will operate on this setting and it is unlikely both have failed, it could be one of the 2 temperature sensors or most likely the PCB. this is not a simple part to replace as you will need to remove the complete fire and break the flue seal. if you follow the link below it will take you to the spare parts\r\n\r\nTruma Ultraheat - Electrical supplementary heater + Spare Parts
