Hi,
Our ten year old Potterton Suprima HE suddenly has no power going to it.
Checked mains supply and all is good.
Removed the Honeywell PCB Code 5110550 and all looked good and dry inside, however around some resistors close to the relays there are scorch marks on the PCB.
My suspicion is with this PCB and am tempted to go out and get a replacement (about £200 each, unless someone can recommend a cheaper supplier?).
However, I don't want to go and do this if it won't completely solve the problem.
My main question to this site is, do these PCBs just stop working and if so, what are usually the causes?
I can understand if there was some water leakage getting in there but it all looks clean.
Any ideas folks. Thanks in advance.
Cheers
Lee.
