Need help?
Do you have a question about the ZJ150 and is the answer not in the manual?
Questions and answers
how do i reset a high pressure switch trip on the compressor of this unit?
To reset the high pressure switch trip on the York ZJ150 compressor, you must reset the alarm causing the “High Pressure Switch 1 Lockout.” This lockout occurs if the high pressure switch (HPS1) trips three times within two hours. Once the issue is resolved and the alarm is manually reset, the compressor operation can resume.
