A 16-year-old Miele built-in refrigerator in Las Vegas stopped cooling because both its inverter board and its power control board had failed. Our technician replaced the two boards with original Miele parts, and the compressor started and the refrigerator returned to normal cooling on the same visit.
| Appliance | Miele built-in refrigerator, 16 years old |
|---|---|
| Location | Las Vegas, NV |
| Symptom | Rising interior temperature, compressor not running correctly |
| Root cause | Failed inverter board and failed power control board |
| Repair | Both boards replaced with OEM Miele parts, system tested and calibrated |
| Result | Compressor running normally, full cooling restored |
The homeowner called Red Rock Appliance Services when the Miele refrigerator stopped holding temperature. The inside was getting warmer by the hour and the compressor wasn't running the way it should.
Miele refrigerators use several electronic boards to manage compressor speed, temperature sensors and cooling cycles. When one of those boards fails, the refrigerator can stop cooling completely even though the compressor itself is healthy.
Our technician ran a full diagnostic of the refrigeration electronics and found:
Electronic components like these can degrade after many years in service, so this combination isn't unusual in an older refrigerator.
Modern Miele refrigerators use an inverter compressor. Instead of running at one fixed speed, the compressor speeds up or slows down with cooling demand, which saves energy and keeps temperatures steadier.
In this refrigerator, both boards had failed after 16 years of service.
High-end refrigerators should be repaired with OEM parts. Generic or aftermarket boards can cause compatibility problems, unreliable operation and further damage to sensitive electronics. Original Miele boards give:
As soon as the new boards were in, the compressor returned to normal operation and the refrigerator started cooling again. The 16-year-old Miele is fully operational and ready for many more years of service.
If your Miele refrigerator isn't cooling, is making unusual noises or shows an electronic error, a proper diagnosis is the first step. We repair Miele built-in and integrated refrigerators, wine refrigerators, freezer columns and other Miele kitchen appliances in Las Vegas, Summerlin, Henderson and Boulder City, including complex electronic, compressor and cooling-system failures.
Common causes are a failed inverter board, power control board, fan or sensor. In this case both the inverter board and the power control board had failed, so the compressor couldn't run correctly.
Usually yes. Built-in Miele refrigerators are expensive to replace and fit custom cabinetry; this one was restored by replacing two boards.

A Summerlin senior living care center asked us to automate its laundry: we installed detergent, softener and bleach dispensing on three commercial washer-extractors and repaired a faulty door lock on one of them.
Two stacked Maytag dryers in a Henderson home started squeaking and their drums began to wobble. Inside we found worn rollers and idler pulleys and a dangerous amount of lint; we replaced the moving parts and cleaned the dryers and vents.
A built-in Whirlpool refrigerator in North Las Vegas stopped cooling because its compressor failed. We replaced it on the R600a system with Vulkan Lokring fittings, no brazing, and saved the owner a new built-in fridge and a kitchen remodel.
An LG refrigerator in Las Vegas stopped cooling because its compressor failed after years of clogged condenser coils. We replaced the compressor and filter drier on the R600a system with Vulkan Lokring fittings, no brazing.
A Las Vegas business got a health department warning for its corroded Scotsman ice bin, and the ice machine kept overfilling or stopping. We fabricated new stainless door frames, replaced the scaled optical sensors and passed reinspection.
A Polin rotating rack convection oven in a Las Vegas bakery would not hold its set temperature. We serviced the burner, found an intermittent flame sensor shutting off the gas, replaced it and cleaned the draft inducer and exhaust blower.
A Las Vegas restaurant's Douglas commercial dishwasher stopped heating on the rinse cycle and its worn control panel had holes in it. A stuck contactor had blown two slow-blow fuses; we replaced both, plus the panel, and rinse heat is back.
A Las Vegas pizzeria's Roto-Flex rotating deck oven swung between flames shooting up and barely any flame. Another company had already replaced the thermostat. We found a clogged combustion blower and fixed it in one visit with no parts.
A Picard RE-8-24 revolving tray oven in a Las Vegas bakery had three problems at once: unstable temperature, squeaking and a drum that stopped turning. Flour had clogged the air intake and worn the drive; we cleaned, replaced the bearings and serviced the chain.
A 38-year-old Sub-Zero 500 Series freezer most companies would have written off: we replaced the compressor, evaporator, heat exchanger and drier with OEM parts and retrofitted it from R12 to a modern refrigerant.
