Baxi 105e No CH but have got HW

NotSure · 24 Apr 2005

My Baxi 105e is playing up. It`s recently been converted from LPG to Mains gas and an external thermostat has been fitted, it has been fine for a week but it will now only operate the hot water system. I have checked all the basics low pressure, power supply, PCB burnt out (had that before on a different boiler), etc and there are no warning lights on but it will not respond at all when the heating is switched on - any ideas?

I'm fairly sure you can swap the thermistors/ thermistor leads over on those for testing purposes> HW to CH and vice versa. If you can and the heating then works and hot water doesnt your CH thermistor is cream crackered
Remember what goes where
2 red wires CH
2 green wires HW
If I'm right in suspecting CH sensor then the part number is 247394
