One of the most common issues of AC which won’t turn off is dirty condenser coils. In this article you will find an answer - how to clean dirty condenser coils in Air Conditioner Viking 186B.
The condenser coils dissipate the heat as the refrigerant passes through the coils. If the condenser coils are dirty, they won’t be able to dissipate the heat as effectively. As debris builds up on the coils, the air conditioner will become less efficient, causing the air conditioner to work harder to cool down. If the coils are significantly dirty, the air conditioner will not be able to maintain the proper temperature, and the compressor will run continuously in an attempt to cool the room. Check the condenser coils to determine if they are dirty. If the condenser coils are dirty, clean them.
Your indoor air handling unit should have an access panel that can be removed to expose the evaporator coil. If necessary, check your A/C owner’s manual to locate the access panel and evaporator coil. Turn the air conditioner off at the thermostat. Remove the screws or other fasteners to loosen the access panel.Place the panel and screws aside where they won’t get lost or separated. Light accumulations of dirt and other material can often be removed using compressed air to blow them loose from the evaporator coil.
- Direct compressed air across the coil in the opposite direction of normal airflow, from the cleaner to the dirtier side.
- For more stubborn pieces, place the air nozzle close to the bottom side of the debris.
- If using high pressure air, direct it either at a 90-degree angle or directly through the fins. This will prevent damage to the fins.
- Maintain consistent airflow across the coil. This will dislodge buildup without forcing it further into the fins and making it more difficult to remove.
- Avoid blowing dust, dirt and debris into the ductwork system or into your home’s living spaces. Wear eye protection to keep the material out of your eyes. If necessary, use a shop vacuum cleaner to collect material as it is dislodged.
If this doesn't work, there could be a defective part that requires a replacement, and you may need to consult a professional.
