When I arrived at unit, I noticed condenser unit wouldn’t work. I found a motor control on inside with fan leg dead. I replaced motor control and unit still didn’t work. I noticed I had 120 v only for incoming voltage and system requires full 240. I traced power back to disconnect box and found one leg of the disconnect box was dead. Replaced fuses in disconnect box. Then I still couldn’t get unit to turn on. I got 24 v from thermostat, I had 24 v at motherboard. When I checked my condenser wires I was loosing power at the low pressure switch leg. Low pressure switch needs to be replaced. It keeps shutting system off as a safety mechanism to protect system from further damage. Switch would need to be ordered when owner is ready. I bypassed pressure switch to contactor to get condenser unit on finally. They need new thermostat and will install once they get.
