Furnace Error Codes: Commercial Ac Repair Ac Heating Service Near Me Emergency Hvac Service Heating Ac Service Near Me Same Day Air Conditioning Service

• E0/101 (Flame Sensor Failure): This code indicates a problem with the flame sensor, which detects whether the furnace is igniting and burning fuel properly. Potential causes include a dirty or faulty flame sensor, a gas supply issue, or a problem with the ignition system.
• E1/102 (Ignition Failure): This code signifies that the furnace is unable to ignite the burner. Possible causes include a faulty igniter, a gas valve problem, or a blocked vent.
• E2/103 (Limit Switch Tripped): The limit switch is a safety device that shuts off the furnace if it overheats. This code suggests that the furnace is overheating due to restricted airflow, a blocked vent, or a faulty blower motor.
• E3/104 (Pressure Switch Failure): The pressure switch monitors the airflow through the furnace. This code indicates a problem with the pressure switch, possibly due to a blocked vent, a faulty inducer motor, or a pressure switch malfunction.
• E4/105 (Gas Valve Issue): This code points to a problem with the gas valve, which controls the flow of gas to the burners. Potential causes include a faulty gas valve, a wiring issue, or a gas supply problem.
• E5/106 (Blower Motor Failure): This code indicates a problem with the blower motor, which circulates air throughout the home. Possible causes include a faulty motor, a capacitor issue, or a wiring problem.

• E1/201 (Low Refrigerant Pressure): This code suggests a refrigerant leak, a blocked refrigerant line, or a faulty compressor. Low refrigerant pressure can significantly reduce the cooling capacity of the AC unit.
• E2/202 (High Refrigerant Pressure): This code indicates high refrigerant pressure, which could be caused by a blocked condenser coil, a faulty fan motor, or an overcharge of refrigerant.
• E3/203 (Compressor Overload): This code signifies that the compressor is drawing too much current. Potential causes include a faulty compressor, a capacitor issue, or a wiring problem.
• E4/204 (Outdoor Fan Motor Failure): This code indicates a problem with the outdoor fan motor, which dissipates heat from the refrigerant. Possible causes include a faulty motor, a capacitor issue, or a wiring problem.
• E5/205 (Indoor Fan Motor Failure): This code indicates a problem with the indoor fan motor, which circulates air throughout the home. Possible causes include a faulty motor, a capacitor issue, or a wiring problem.

3. Check Basic Components: Inspect readily accessible components, such as air filters, vents, and outdoor coils. A clogged air filter can restrict airflow and trigger error codes. Ensure that vents are not blocked and that the outdoor coil is free of debris.
4. Inspect Wiring and Connections: Check for loose or damaged wiring and connections, especially around the control board and other electrical components.
5. Contact a Professional: If the error code persists or if you are uncomfortable performing any troubleshooting steps, contact a qualified HVAC technician. Attempting complex repairs without proper training can be dangerous and can potentially cause further damage to your system.
