DriStorm / Suntec Dehumidifier Compressor Capacitor
55 µF 450 VAC – Part SDP0104009

Replacement compressor run capacitor for select DriStorm and Suntec commercial dehumidifiers using part number SDP0104009.

This capacitor helps the refrigeration compressor start and operate efficiently by supplying the electrical phase shift required by the compressor motor. A weak or failed capacitor may prevent the compressor from starting, cause intermittent refrigeration operation, or make the compressor overheat.

Known Application

Used on select DriStorm and Suntec commercial dehumidifiers that specify compressor capacitor part number SDP0104009.

Possible Symptoms of a Failed Compressor Capacitor

• Compressor hums but does not start
• Fan operates but the machine does not produce water
• Compressor starts slowly or cycles off unexpectedly
• Compressor draws excessive current or overheats
• Dehumidifier trips a breaker or overload protector
• Capacitor housing is swollen, leaking, split, or heat damaged
• Capacitance tests below the specified 55 µF rating

Important Replacement Guidelines

• The replacement capacitance should match the original 55 µF rating.
• A capacitor with the same or higher AC voltage rating may be acceptable when properly sized.
• Do not replace a 55 µF capacitor with a substantially different microfarad rating.
• Verify that the replacement fits securely inside the available mounting space.
• Transfer each wire to the corresponding terminal position used on the original capacitor.

Installation Safety

1. Disconnect the dehumidifier from electrical power.
2. Allow the machine to remain unplugged before opening the cabinet.
3. Properly discharge the existing capacitor before touching either terminal.
4. Photograph and label all wires before disconnecting the original capacitor.
5. Install the replacement capacitor securely in the original mounting location.
6. Confirm that all terminals are tight and insulated from the cabinet.
7. Reinstall all covers before reconnecting electrical power.

Before Ordering

• Confirm part number SDP0104009.
• Verify the original capacitance is 55 µF.
• Confirm a 450 VAC rating or other approved replacement rating.
• Compare the capacitor diameter and overall height.
• Compare the two-terminal electrical connection.
• Inspect the original mounting strap or bracket for reuse.
