GE Dehumidifier: not cooling

Professional Repair Guide

What is this symptom?

Experiencing issues with your GE dehumidifier not cooling? This common problem may stem from low ambient temperatures, a dirty air filter, or faulty compressor components. If your unit runs without effectively removing moisture, read on for solutions to restore its functionality.

Urgency: Medium

Important Tips for GE Models

  • Official GE support acknowledges that if the unit runs but does not collect water, the condition often indicates a deeper issue and recommends basic resets and checking humidity settings before repair. (

Possible Causes

Low ambient temperature causing freezing or inefficiency of the refrigeration system

How to Identify: Unit runs with little/no water collection and room temperature is low; frost or ice buildup on coils may be visible. Source mentions poor performance of compressor-based dehumidifiers in cold weather. turn0(

Part: evaporator coils / refrigeration system

Dirty or clogged air filter restricting airflow

How to Identify: Reduced airflow through intake/exhaust, dusty filter visible, unit runs but does not effectively remove moisture. turn0(

Part: air filter

Faulty compressor or compressor start components

How to Identify: Fan runs but compressor does not start (no typical compressor noise; unit has no dehumidification. (

Part: compressor, start capacitor/PTC relay

Airflow blockages around intake/exhaust

How to Identify: Unit placed close to walls or objects blocking airflow; visible obstructions. turn0(

Part: air intake/exhaust pathways

Mis-set humidity target or naturally low humidity

How to Identify: Humidity setting is higher than room humidity, or space is already dry. turn0(

Part: humidistat/settings

DIY Solutions

Ensure Proper Ambient Temperature

Easy 5 minutes
  1. Move the dehumidifier to a warmer environment.
  2. Allow any frozen coils inside the unit to thaw completely before restarting.

Clean or Replace the Air Filter

Easy 10-20 minutes
Tools Needed: vacuum cleaner or soft brush, mild soap and water
  1. Turn off and unplug the unit.
  2. Remove the air filter according to the user manual.
  3. Vacuum or wash the filter (if washable) and allow it to dry fully before reinserting.
⚠️ Safety First: Ensure power is disconnected before accessing internal components.

When to Call a Professional

Compressor does not start and simple filter/temperature fixes do not improve performance
Unit displays unusual noises (loud buzzing, grinding) or vibration during operation
Visible refrigerant leak or frost that recurs frequently

Preventive Maintenance

  • Regularly clean the air filter: Restricted airflow that reduces moisture removal efficiency
    Frequency: monthly or as needed
  • Ensure adequate clearance around the unit: Airflow blockage that can reduce performance
    Frequency: ongoing

Common Issues Reported by Users

  • Dirty air filter restricting airflow
  • Faulty compressor not functioning properly
  • Refrigerant leak causing insufficient cooling

User Suggested Solutions

  1. Clean or replace the air filter. Turn off the dehumidifier, remove the filter, wash it with warm soapy water, and let it dry completely before reinstalling.

  2. Check the compressor. If it is not running, listen for any unusual noises. If it appears faulty, it may need to be replaced.

  3. Inspect for refrigerant leaks. If you suspect a leak, look for oily residue around the coils. A professional technician should be called to repair and recharge the refrigerant.
