Re: Dodgy Thermostat
was it working BEFORE you changed the thermostat?????
If “yes” likely you’ve wired it wrongly
If “no” you need to check that there is continuity from the mains-plug to the compressor-motor….if you check this with a multimeter on “ohms” range, (UNPLUGGED, of course!) you may be able toturn the ‘stat control sufficiently to switch on-off and confirm it works…..but in any event, if you have continuity to the motor, but it doesn’t run, it could well be kaput.
