Has anybody else experienced alot of problems with these units circuitboards? Im getting an E1 error code on a brand new system I installed today, but high pressure protection doesnt make any sense as the outdoor unit wont even turn on. Ive had to change out boards 3 times in the last year so Im thinking that may be my problem here today. Anybody have any experience with these systems & an E1 error code?

Many techs report frequent circuit-board failures causing E1 errors. On new installs, E1 is usually a communication or wiring fault, not real high-pressure protection. If the outdoor unit won’t start, check power, sensors, and indoor-to-outdoor wiring—often the true cause.
