If the compressor isn't running on your Ultra-Aire Dehumidifier while the fan is, and dehumidification is active, potential causes include: * A defective compressor run capacitor. * A loose connection in the compressor circuit. * A defective compressor overload. * A defective compressor. * An open defrost thermostat.
What to do if Ultra-Aire 98H Dehumidifier fan and compressor not running?
If neither the fan nor the compressor is running when dehumidification is active, the Ultra-Aire Dehumidifier may be unplugged or the outlet may not be receiving power. WARNING! ELECTRICAL SHOCK HAZARD: ELECTRICAL POWER MUST BE PRESENT TO PERFORM SOME TESTS. THESE TESTS SHOULD BE PERFORMED BY A QUALIFIED SERVICE PERSON. Also, to troubleshoot control related issues, detach field control wiring connections from the terminals on the main unit. Connect the 24V and FAN terminals together; only the fan should run. Disconnect the terminals. Connect the 24V and DEHU terminals together; fan and compressor should run. Disconnect the terminals. If this test works, the main unit is working correctly from a control standpoint. Reconnect field control wiring to the terminals on the main unit. Remove the...

The Ultra Aire 98H and 120H are ventilating dehumidifiers designed to integrate into existing heating and cooling systems, providing comprehensive solutions for comfort, health, and property protection. These devices offer dehumidification, optional fresh air ventilation, and air filtration.
The primary function of the Ultra Aire 98H and 120H dehumidifiers is to remove excess moisture from the air, thereby controlling relative humidity levels within a structure. This helps prevent issues such as mold growth, dust mites, and discomfort associated with high humidity. The units are designed to be installed indoors in spaces protected from rain and flooding. They can be ducted to an existing HVAC system, drawing air from a dedicated indoor air return and supplying dehumidified air to the HVAC system's supply. An optional fresh air ventilation feature allows for the introduction of outside air, which can be programmed for specific times and frequencies based on the residence's size and occupancy. This feature is particularly useful for year-round drying, even in cold climates or when dew points are low. The units also incorporate air filtration, equipped with a MERV-13 filter to improve indoor air quality.
