LG LFX25973ST French Door Repair

Most common issues on this model

Evaporator fan and air path
Defrost heater and sensor
Dispenser water flow and ice output
Door gasket and door-ajar alarm
Condenser fan and coil

The LFX25973ST is an older LG 3-door French door refrigerator. It has frost-free cooling and a door-ajar alarm, and it was sold in two finishes. Units like this are often in kitchens that have been in service for years, so wear on seals and fans is a regular topic.

For cooling, we begin with the evaporator fan and the air path between the freezer and the fresh food section, then the defrost heater and sensor. If the alarm sounds with the doors shut, we check the gasket, the hinges and the door switch. If water or ice is part of the complaint, we check the supply line and the valve.

Because it is a legacy model, we read the model and serial from the label and confirm the part before ordering. We give a written price and availability first, and we cover the finished repair with a 30-day workmanship warranty.

LFX25973STLFX25973ST questions

What do you check on an older LFX25973ST that is not cold?

We check the evaporator fan and air path first, then the defrost system and the condenser fan and coil. We also look at frost on the evaporator cover, which is the usual sign that the defrost system is not clearing it.

Why do old door gaskets matter?

A worn gasket lets warm air in, so the unit runs longer and may frost. We check for gaps and tell you if a gasket is the cause. Parts for legacy units can take longer to arrive, so we also tell you the expected wait before we start.

Do you stock parts for older LG refrigerators?

We confirm the exact part from the label and tell you availability and the written price before any work starts. For legacy units we also tell you the expected wait for the part.
