Client had a electrician come out and replace the breaker and disconnect. System had proper power going to it, but from the fuses being bypassed before it sent to much current to the capacitor, contacter and hard start kit. Not allowing the system to start. Could bump the contacter and it would try to start up but from the other start assist devices being out it could not start fully. Replaced the contacter, capacitor and hard start kit. System fired right up and is cooling at this time. Unit is a 25 year old day and night. 17 degree temperature split system is operating at this time.
