A friend damaged their heater controller PCB during disassembly, so I patched it back together and replaced the broken switches/pots.
Whilst i had it disassembled I traced out the circuit and reverse engineered the PCB because I could and it may be useful to others
The original Switches / Potentiometers have been replaced with part: P170SP1-FC15AR10K
Details
The closest to the original potentiometers that I stumbled upon recently after completing the project are; Bourns Pro Audio, PTM90 Series pots. [Ref. http://www.potentiometers.com/PTM90.cfm?link=BP]
