Side by Side Refrigerator Repair

Rarely. On a twin cooling model each compartment has its own evaporator and its own airflow, so a single failed side usually means a fan, a damper or a sensor on that side — not a refrigerant fault. Refrigerant loss almost always shows as both sides losing performance together.

The order we check it is: water supply and inlet valve, then the filter, then the fill tube for a freeze blockage, then the ice maker module and its thermostat. On hard water a scaled inlet valve is the most common cause and one of the least expensive to fix.

The compressor itself rarely fails. What does fail is the inverter drive board that runs it, and that is a board-level repair or replacement rather than a sealed-system job. It needs proper electronic diagnosis — a technician who only carries gauges cannot tell you which of the two it is.

Most modern units claim a wide input range, and on a stable supply that is genuinely enough. Where supply voltage swings — and across much of the NCR it does — a stabiliser is cheap insurance against an inverter board that costs many times more to replace.

It does not, in normal use. A sealed refrigeration system should never lose gas. If yours is low, there is a leak, and topping it up without finding that leak simply means you pay again in a few months. We trace and repair the leak first, then vacuum and charge by weight.
