Unveiling The Mystery: Why Your Mitsubishi Electric Heater Is Blowing Cold Air

Is your Mitsubishi Electric heater leaving you shivering instead of providing warmth? If so, you’re not alone. Many homeowners face the puzzling issue of their heater blowing cold air. To resolve this issue, it’s crucial to understand the underlying causes. This blog post will delve into the reasons why your Mitsubishi Electric heater may be blowing cold air and provide practical solutions to restore its warmth.

Common Causes and Solutions

1. Thermostat Malfunction

Cause: A faulty thermostat can disrupt the communication between the heater and the temperature setting.

Solution: Check if the thermostat is set to “heat” mode and the desired temperature is higher than the room temperature. Replace the thermostat if necessary.

2. Clogged Air Filter

Cause: A clogged air filter restricts airflow, reducing the heater’s ability to generate warm air.

Solution: Regularly clean or replace the air filter to ensure optimal airflow.

3. Dirty Evaporator Coils

Cause: Dust and debris can accumulate on the evaporator coils, reducing heat transfer efficiency.

Solution: Schedule a professional cleaning of the evaporator coils to remove the buildup.

4. Refrigerant Leak

Cause: A refrigerant leak can deplete the system’s refrigerant levels, hindering its ability to absorb and release heat.

Solution: Contact a qualified HVAC technician to locate and repair the leak.

5. Electrical Faults

Cause: Electrical faults, such as loose connections or damaged wires, can disrupt the heater’s operation.

Solution: Have a certified electrician inspect and repair any electrical issues.

6. Frozen Condenser

Cause: Extreme cold temperatures can cause the condenser to freeze, preventing it from releasing heat.

Solution: Thaw the condenser by turning off the heater and allowing it to sit for several hours. Do not use a hair dryer or other heating device to speed up the thawing process.

7. Incorrect Installation

Cause: Improper installation can result in inadequate airflow or incorrect wiring, leading to cold air blowing.

Solution: Ensure that the heater is installed according to the manufacturer’s instructions by a qualified technician.

Additional Troubleshooting Tips

• Check the circuit breaker: Ensure that the circuit breaker supplying power to the heater is not tripped.
• Reset the heater: Turn off the heater for a few minutes and then turn it back on to reset it.
• Contact Mitsubishi Electric support: If the above solutions do not resolve the issue, contact Mitsubishi Electric support for further assistance.
