Re: Creda 37445 No heat
There are not two thermal cut outs. One is a one shot thermal cut out, the other is the temperature control, cycling thermostat. 😉
Usually the one shot will have tripped, a simple continuity test is all that is needed, they should both be closed circuit.
THESE are what you need.
There is another stat or stats hidden away inside fixed to the vent but they don’t often fail.
PS. Take great care not to press the bases of the new stats.
