Re: hotpoint ff65
Common fault is usally the yellow thermistor 2601683.
I got this off Hotpoint engineer.
Test mode
To run test with the appliance switched off at mains. Press and hold the fast freeze button then switch on the mains.
Evaporator defrost heater runs for 10secs.
Gutter heater runs for 10 secs.
fast freeze led on for 10 secs.
evaporator fan runs for 25 secs.
Returns to normal mode after test.
if the module detects an error the high temp warning light (red) will flash, one second on and one second off, until mains is disconnected
Hopes this helps
