Potterton fan permanently on

rodbirtles · 12 Sep 2012

Hi. I have a Potterton performa 28i, at least 10 years old, regularly serviced. The fan seems to be permanently on when switched to hot water only, and all the temperature lights are on (not flashing) all the time. Hot water runs fine. Any suggestions?

I dont remember seeing that fault before.

You should check the resistance of all the temp sensors.

If they are OK then it may be a PCB fault. But thats an expensive item and probably best to have professionally diagnosed rather then blindly changing it.
