Dehumidifier fan runs but compressor cycles on and off rapidly every few minutes.

Safety first: Unplug the unit before accessing internal components. Compressor and capacitor terminals can be hazardous.

• Step 1 – Clean condenser coil: Remove the rear cover and gently vacuum dust from the warm condenser coil. Improved airflow helps keep the compressor cool.
• Step 2 – Check room temperature: Extremely high ambient temperatures can cause short cycling. Improve ventilation around the unit.
• Step 3 – Inspect overload and wiring: At the compressor, check the overload protector and wiring for signs of overheating or loose connections. Replace the overload if it appears heat-damaged.
• Step 4 – Allow cool-down: Let the unit rest unplugged for 30–60 minutes, then restart and observe. Persistent short cycling suggests a failing compressor or control issue.

Compressor short cycling can quickly damage the unit. If cleaning and overload replacement do not resolve it, consult a professional technician.
