I have an SCI-120A and been talking to their suppor team and he says the compressor is bad. When I energize the system, I watch the head pressure go up to over 200 psi, and the low pressure side started at about 100 psi and went up too about 150psi.

The evaporator fan does not come on, so I put a fan in front of evaporator and that would bring the low side back down to about 100 psi. I also noticed that the hot gas bypass valve is energized. This does not make any sense to me. They do not send you much information on their systems.
