If the Quincy QPNC354 dryer turns on but the fan and control panel are not working, follow these troubleshooting steps:
1. Check the fan operation – Ensure the fan is functioning correctly. If not, inspect for electrical or mechanical issues.
2. Check the pressostat (pressure switch) – Verify its operation and calibration.
3. Check voltage and power supply – Ensure proper line voltage is available. If the voltage is too low, contact the electric power company.
4. Inspect motor starting system – Check the running and starting relays and any condensers, as a defective starting system may prevent fan operation.
5. Check for refrigerant leaks – If the cooling circuit is not working properly, the fan may not operate. Repair leaks and recharge refrigerant if needed.
6. Check overload protection – If the motor cuts out due to overload, refer to causes such as excessive temperature or improper refrigerant charge.
7. Wait after restart – If the machine was switched off and restarted too quickly, wait a few minutes before trying again to allow pressure balancing.
If the issue persists, contact an authorized technical assistance center.
