Defrost Timer - follow on
Thanks to those who helped. A new timer arrived today and confident that I
understood the circuit I quickly fitted it. Shock - horror - the compressor wouldn't operate. I refitted the old timer - manually wound it round - still it wouldn't operate. Out with the meter - found the circuit to be open circuit to the motor. What had I done???? Took the terminal cover off the compressor to see if I could track down the fault - plugged it in again - and it fired up. Had I disturbed a connection? No - I did the job so quick and the motor was so hot that the compressor stalled when I applied power and then tripped the overheat trip. Working fine now. |

You should have worked more slowly, then charged yourself for the second hour. -- Graham. %Profound_observation% |
