Since you have a capacitance meter and you are not getting any

best bet the starting capacitor is your problem.
Some places that sell parts will test the old for you.
I'm not sure about the 25 ohm resistor block. Does the block actually
state 25 ohm or is that just the measurment your getiing?

Hi Doug,

It is printed on the block that it's 25 ohms and that is what I am
getting.
I will have a look again and see if I can find the thermostat. There is
a dial
on the front panel that controls the temperature " 1 to 5" but I
presumed this was just another variable resistor. I'm afraid the owners
manual is not very helpful.
