LG Heat Pump Error Code E295

E295 indicates a suction temperature sensor error, specifically an OPEN or SHORT condition in the sensor circuit. The suction temperature sensor monitors refrigerant temperature at the compressor inlet, and when the signal falls outside the valid resistance range, the control board triggers this fault. The system may restrict operation or shut down entirely to protect the compressor. A technician diagnoses this by checking the sensor connector and measuring resistance against a reference table.

Running the unit with an active E295 fault is not recommended. The suction temperature sensor provides data the control board uses to protect the compressor from damage caused by liquid refrigerant or overheating conditions. Without a valid sensor signal, the system cannot make accurate control decisions, which increases the risk of compressor damage. Most units will limit or halt operation automatically, but resolving the fault promptly is the safest course of action.

Repair costs vary depending on what has failed. If the issue is simply a loose or corroded connector, the cost may be limited to a service call fee, typically in the range of $75 to $150. A replacement suction temperature sensor generally costs between $20 and $80 for the part, plus labor. If the control board has failed, parts alone can range from $150 to $400 or more, making total repair costs significantly higher.

The first step, checking the sensor connector for a loose or corroded connection, is something a knowledgeable DIYer can perform safely with the unit powered off. However, measuring sensor resistance accurately and tracing wiring faults requires a multimeter and familiarity with the system's wiring layout. Replacing the sensor or control board involves working near refrigerant components and electrical circuits that are best handled by a qualified technician.

A power reset may temporarily clear the fault display, but the code will return if the underlying sensor or wiring problem has not been corrected. If the sensor has failed or there is a wiring fault, the control board will detect the out-of-range condition again as soon as it attempts to read the sensor. A reset is only a useful step if you have already identified and repaired the root cause.
