REFRIGERATOR · CASTRO VALLEY
Refrigerator not cooling in Castro Valley? We fix it.
A fridge that runs but will not get cold is one of the most common calls we run, and it almost always traces to one failed part, not a dead unit. The compressor, the boards that drive it, and two small fans all have to do their job for cold air to reach your food. When one quits, the box warms up. We find which one and tell you the number before we touch anything.
We handle refrigerator not cooling repairs across Castro Valley, from Five Canyons, Palomares Hills, Castro Valley Village to the surrounding neighborhoods.

Why this happens
What we look for first.
- Control board not powering the compressor. The main control board is the brain that tells the compressor to run. When the board fails or loses the output that drives the compressor, the compressor never starts and nothing gets cold, even though lights and fans may still work. We meter for voltage at the compressor circuit and confirm the board is the dead link before we condemn it. Repair pricing is provided in a written estimate after the on-site diagnosis.
- Inverter board failure. Many newer fridges run a variable-speed compressor driven by an inverter board. The inverter takes the control signal and runs the compressor at the right speed. When it fails, the compressor will not start or will not hold a run, and cooling stops. We test for the drive output and check the compressor windings before replacing the board. Repair pricing is provided in a written estimate after the on-site diagnosis.

Before you call
Is your fridge worth repairing?
Repair price depends on what failed and how the unit is built. If your refrigerator cost under $1,000 new, the repair math may not work. We diagnose the unit on site and provide the written repair estimate before any work starts.
Premium built-ins in the Sub-Zero, Monogram, and Thermador class are designed to be serviced. We diagnose the fault and help you compare the written repair estimate with replacement.
Two free checks before you call: vacuum the condenser coils, and run the dollar-bill test on the door seal by closing the fridge on a bill and seeing how easily it slides out. If the power blinked recently, give the compressor a full day before deciding it is dead. If the fridge really is done, put that money toward the next one instead. Our other trade is heating and cooling, and a replacement assessment visit for an A/C, furnace, or heat pump is free.
