Category: Commercial Appliance Repair

Type: Commercial Refrigeration Repair

Customer: Local Bakery

Symptoms:

The customer, a local bakery, reported that his walk-in cooler was over freezing food stored in it. The desired temperature setting for a bakery is around 38-39 degrees Fahrenheit. This walk-in cooler’s temperature was at 33.5 degrees Fahrenheit when measured with a digital thermometer.

Repair:

After an inspection, our technician realized that temperature control was missing, and the unit was running on pressure control installed on the roof. Since pressure control is not as precise when adjusting temperature as the main temperature control, the unit was freezing food stored in it.

Our technician recommended that a digital temperature controller with a cabinet sensor be installed since it allows for a very precise temperature setting. Additionally, it has a manual defrost feature, so defrost can be scheduled at any time and for any duration at a pre-specified schedule.

Type: Sub-Zero Refrigerator Repair

Customer: Residential Customer

Sub-Zero Refrigerator Repair

Symptoms:

A residential customer called us and explained that their Sub-Zero refrigerator was not cooling well enough.

Repair:

Out technician measured the temperature inside the refrigerator, and it was just 54 degrees Fahrenheit. He then used the gauge to find out the pressure of Freon inside the system and realized it was too low. Pressure was negative instead of the regular pressure of +20 psy. He performed deep chemical service of the condenser coil, and after adding 3.5 ounces of Freon, the pressure normalized, and the refrigerator started cooling normally again.


Category: Washer Repair

Type: Top-load Kenmore Washer Repair

Customer: Residential Customer

Kenmore Washer Repair

Symptoms:

A residential customer complained that their washer produces grinding sound.

Repair:

Out technician examined the washer and heard the loud grinding noise coming from inside the washer. Our experience shows that the most common cause of this grinding noise is that the motor coupling becomes crushed. The technician disassembled the unit, replaced the motor coupling and reassembled it back. After he turned it on, the washer started working just fine.
