Sub-Zero Refrigerator Repair — Temperature Sensor Replacement and Alarm Fix (Zip Code 92131)
Recently, a technician from Marshall Appliance Repair completed a same-day repair of a premium Sub-Zero refrigerator in the zip code 92131 area, San Diego.
The customer contacted us because the refrigerator was constantly making a loud beeping sound and displaying incorrect temperature readings, causing the cooling system to operate improperly. This is a common sign of a failing temperature sensor.
Our technician performed a full diagnostic and quickly identified the issue — a faulty temperature sensor. The temperature sensor was replaced the same day with a genuine Sub-Zero part, restoring normal operation and completely eliminating the alarm sound.
Additionally, on the same day, we performed preventive maintenance by cleaning the condenser coils to improve performance and extend the lifespan of the refrigerator.
As discussed with the customer, we will order a new water filter and return to install it during a scheduled follow-up visit.
