Wishing everyone on tgmhis forum a very happy Christmas!!
I am working on a combi boiler which has problem with heating only. Water is heating normally. Here are the symptoms
1. Signal from thermostat is not firing the boiler. It does not make any sound when heating is on from thermostat.
2. Heating Dial on the boiler does not trigger temperature change on the display screen when turned. Water dial does change the temperature.
3. Low temp/ high temp test in service mode works and radiators are heating.
Given above,
1. Could this be an issue with thermo stat? Does high heat test in service modw work if thermo stat is broken?
2. Could there be an issue with the heating dial on the boiler?
Please help.
Thanks
