What to do if my Great Lakes Air Products GPS-500 Dehumidifier has a cycle or sequence failure?
- BBridget HarrisAug 5, 2025
If your Great Lakes Air Products Dehumidifier experiences cycle or sequence failures, potential causes include low feed voltage, issues with process, check, or solenoid valves, timing card failure, or the dewpoint meter not signaling in a dewpoint demand only system. Refer to the ELECTRICAL CONNECTION section for low feed voltage, the OPERATION section for valve failure, the SEQUENCE CONTROLLER section for timing card failure, and the Dewpoint Demand Controller section for dewpoint meter issues. Also, check Valve Integrity and Intermittent Cycle Problems sections.
