Hello out there,
I've got a potterton performa 28 -4 1/2 years old.
For the last two weeks it keeps getting an ignition fault when it calls for DHW or central heating. this can be reset albeit after half a dozen attempts.
The fan starts and the air pressure switch switches. When it switches it turns the fan off - when the fan stops the APS switches the other way and turns the fan on again. This repeats several times and then the ignition fault comes on. I've checked the voltage and everything looks fine.
If i operate the microswitch independent of the APS it does the same thing.
Is there something on the PCB that latches the fan motor or am i overlooking something.
All answers gratefully received.
