Why is my Topaz Air Conditioner compressor running but not cooling enough?
- B
  Beth VangAug 11, 2025
  If the compressor in your Topaz Air Conditioner runs, but the condenser fan does not, and you're experiencing insufficient cooling, start by checking for any loose or defective wires and repair them. Replace any shorted or open condenser motor capacitors. If the motor is bad, replace it. Insufficient airflow through the evaporator coil could also be the cause. Check for improper blower rotation and correct it if necessary. Replace a dirty air filter, clean a dirty evaporator coil, remove any obstructions, and defrost any ice on the evaporator coil. If the refrigerant is low, repair the leak and recharge it. Finally, ensure that the unit is properly sized for the load; if not, consider adding additional air conditioners.

How to fix a noisy Topaz TZ-12B Air Conditioner?
- M
  Mary GravesAug 15, 2025
  If your Topaz Air Conditioner is operating noisily, it could be due to several factors. For TZ-60B3&4 models, check for improper compressor rotation and correct it if necessary. Inspect all panels and components to ensure they are securely fastened, tightening as needed. Also, check motors, blower wheels, drives, bearings, and shafts, tightening them as required. If the noise persists, the motor, compressor, or bearing might be bad and need replacement.
