WHP / Proline TDC75 (8540 635 15001) T/dryer stats.

[leavemetogetonwithit]

The two stats that fix on the heater with a clip. Have got 4812 259 28681 as replacement from Masterpart. Just wondering … old ones were identical; no colour markings and same number on contact surface (A260).
New stats have one plain (A260) and one green (A210).
I’m thinking they must have fitted it wrong when manufactured.
Does it matter which one should go to top?
Appreciate any help.
Mike.

Thanks bzz. However the ones on this machine had all tag insulators coloured black 🙁 .
I noticed that the lower stat was connected in line with a heater terminal so I think that would be the safety stat. But which one should that be, green or plain?

Many thanks bzz, that’s really all I needed to know. I’ll put the plain one directly in line.
I did think it a bit unusual that both stats had gone o/c.
I guess that it must have been cycling on the exhaust stat until now.
Perhaps I’d better order up one of those too as it’ll probably be pretty burnt out. Presumably the two safety stats had to fail in turn on the one overheat occasion.

i see they call it a fluff thermostat, it probably only operates when a blockage in filter reduces the airflow so that the exhaust stat does’nt really get the heat.

Thanks for good info. I’ll give it all a clean out.

Went back here today. Turned out there was a green paint spot on one of the insulators and white spots on the other three. Didn’t note that first time round 😳 . So I fitted them accordingly. All OK now. Asked customer a few Q’s. She said it did used to get very hot (surprise, surprise) and she was always opening the door before the prog. finished and taking the clothes out steaming hot! :rolls:
Thanks again bzz.
Mike
