Frost coating the freezer's back wall, a sheet of ice under the deli drawer or freezer floor, or a fridge section that turns warm while the freezer still freezes — classic signs the defrost system has stopped doing its job. We fix this in Aliso Viejo — usually same-day.
If your refrigerator just quit in Aliso Viejo, you don't need a generalist — you need an LG specialist. Glenwood, Westridge, and everything in between — Aliso Viejo's townhomes and single-family homes keep our LG team busy.
The most common cause. LG refrigerators melt frost off the evaporator several times a day; when the defrost circuit fails, ice accumulates until it blocks airflow and the fridge section goes warm. We test the heater, defrost sensor, and control output on the spot.
A gasket with even a small gap feeds humid Orange County air into the cabinet all day. The frost pattern usually points right at the leak.
Melt water can't leave, refreezes, and builds a sheet of ice on the freezer floor that eventually leaks onto the kitchen floor. Clearing and treating the drain fixes it.
The motorized damper between the freezer and fridge sticks open, over-freezing the fresh-food section and icing the vents.
A weeping fill valve sprays water past the ice maker, glazing the ice bin and the freezer wall behind it.

Defrost failures are diagnosed by measurement, not guesswork: we test the heater's resistance, the sensor's response, and the control board's defrost output in one visit and carry the common LG defrost parts on the truck. As a factory authorized LG service company, we fix the cause — not just melt the symptom with a hair dryer. We're in Aliso Viejo regularly — most repairs are completed the same visit.
A full manual defrost (24 hours, doors open, towels down) clears the symptom — but if the defrost circuit has failed, the ice returns within a week or two. Use it as a stopgap to keep food cold, not as the fix.
The evaporator sits behind that wall. Frost there means defrost cycles aren't happening (heater/sensor fault) or humid air is getting in (gasket). Either way it's fixable in one visit, usually without major parts.
