Dehumidifier Parts

Common Dehumidifier Parts & Symptoms

Dehumidifiers fail in predictable ways, and most repairs come down to a handful of core parts. A unit that won't dehumidify, makes noise, or leaks water is usually fixable with the right OEM part and 30 minutes of your time. Repair Clinic stocks genuine dehumidifier parts for all major brands -- GE, Frigidaire, Kenmore, Honeywell, and more.

Start with your model number (found on the nameplate inside the unit or on the back). Enter it into our parts finder and you'll see exactly which parts fit your machine. We carry complete repair kits and individual parts, same-day shipping on most orders.

• Compressor not running / unit won't dehumidify: Compressor, run capacitor, start relay, or control board
• Fan motor not spinning / no airflow: Fan motor assembly, motor capacitor, or control board
• Bucket filling too fast or won't shut off: Float switch, overflow switch, or humidity sensor
• Incorrect humidity reading / won't cycle on/off: Humidity sensor (thermistor) or humidistat control board
• Water leaking from unit: Drain hose, O-ring seals, bucket gasket, or float valve

Dehumidifier Parts & Repair Guide

Why is my dehumidifier not removing moisture?

The compressor is the heart of a dehumidifier -- it cools the coils so water can condense out of the air. If your unit runs but humidity stays high, the compressor may have failed (a sealed-system repair), the capacitor is dead (motor won't kick into cooling cycle), or the humidity sensor is giving false readings. A run capacitor replacement is one of the most common and cheapest fixes; if the compressor itself is sealed-system failure, that's a bigger job. Always verify the humidity setting and bucket/drain path first -- a full bucket will prevent the unit from running.

What does the float switch do, and when does it fail?

The float switch is a safety device inside the bucket that stops the compressor when water fills up. It prevents overflow and keeps the unit from running dry. If your dehumidifier shuts off randomly or won't turn back on after you empty the bucket, the float switch may be stuck or the overflow switch (a separate safety component) has tripped. Both are inexpensive parts, and Repair Clinic carries them for every major dehumidifier model.

How do I find my dehumidifier model number?

Look for the nameplate on the back or inside the bucket area -- it'll show a model number starting with letters (GE, Kenmore, etc.) followed by numbers. Write down the full model number and use our Dehumidifier Parts finder to pull up exact-fit parts. Some dehumidifiers have the model number on the bucket support or near the drain connection. If you can't locate it, a photo of the nameplate can help our support team identify the right parts.

Can I replace the compressor or sealed system myself?

Sealed-system parts (compressor, condenser, evaporator) are factory-sealed and require a technician license in most states to handle refrigerant. We stock the parts so you can send your unit to a local HVAC tech, or you can handle easier repairs like replacing the capacitor, fan motor, float switch, or humidity sensor. Always check your dehumidifier warranty before opening it -- some coverage is voided by DIY service on sealed systems.
