Run capacitor failure
Hi
What would be the results of a failed run capacitor on a voltage type relay??
The compressor is a Prestcold PK50 (240 volt capacitor start and capacitor run)
When i start the compressor a current is detected on the start cappacitor for a short time (as normal)
but i cannot detect a current draw through the run cappacitor.
I have checked the run capacitor (5uf) and it was open circuit, i have replaced it with a new one but the compressor is struggling, the amps gradually rise from 4amps upwards and eventually (within 5 mins) re-energises the start relay and trips the clixon.
Please advise if a current reading should be measured through the run capacitor and what if any damage may have occur due to the failed run capacitor.
many thanks
