- Controls the circulating fan in heat pump, air conditioning and forced air systems. Delay on make lets air reach proper level prior to turning on the fan. Off delay timing function continues to run the fan at the end of the heating/cooling cycle, thereby purging ducts of residual air and increasing system efficiency.
Product Features- Low cost open board design
- High power, relay output
- Dual function fan delay timer
- Controls the circulating fan in heat pump, A/C and forced air systems
- OFF delay purges ducts of residual air
- ON delay allows air to reach the proper comfort level prior to energizing the fan.
- Replaces thermal time delays
Mode of Operation - Power must be applied before and during the time delay period. When the initiate contact closes, the load energizes and remains energized as long as the initiate contact is closed. The time delay begins when the initiate contact opens. At the end of the time delay period, the load is turned off. If the initiate contact re-closes during the time delay period the load remains energized and the time delay is reset to zero. Removal of the input power during the delay turns off the load and resets the time delay to zero. A one second interrogation delay is provided to avoid nuisance trips due to thermostat bounce or tampering.

Maintenance & Troubleshooting:
- This capacitor is typically replaced when diagnostics indicate a run capacitor is out of specification or when motor operation issues are traced to the dual run capacitor (diagnostic procedures are not provided in the supplied sources).
- If issues persist after replacement, confirm the installed capacitor matches the required MFD and voltage ratings and that all connections are correct per the equipment documentation.
Certifications & Compliance:
- Manufacturer listing states UL & cUL for these capacitors.
User Reviews & Q&A Summary:
- Review themes commonly describe it as a correct replacement capacitor that restores cooling operation when a failed capacitor is replaced.
- Many comments focus on getting the right part quickly and returning equipment to service, with frequent notes about straightforward replacement once the correct rating is confirmed.
