Top quality repairs and service for all Sub Zero appliances


Here our technicians understand how to eliminate electrical component failures before assuming and sealed system failure.

 

In a refrigerator our technicians understand the following circuits

  • Refrigerator system circuits
  • Defrost system circuits
  • Mullion/Stile anti-sweat circuits
  • Ice maker circuits

We test the various loads that provide heat, lights or motion. We test switches that control flow & current on and off status.

Common loads
  • PTC relay
  • Compressor
  • Condenser fan motor
  • Evaporator fan moto
  • Defrost time motor
  • Defrost heater
  • Defrost control board
  • Main control board
Common Switches
  • Defrost timer
  • Thermostats
  • Overloads
  • PTC relays
In order to accomplish the above our technicians fully understand how a sub-zero refrigerator system works. Both parallel circuits and series circuits in each refrigerator system in various models.

In sub-zero refrigerators and many other common refrigeration systems we have found the following sealed system failure types.

Common points of refrigerator failure
  • Evaporator inlet temperature
  • Refrigerator storage temp
  • Condenser inlet temp
  • Condenser outlet temp
  • Suction line temp
  • Unusual refrigerator noises
  • Wattage variations
  • Amperage variations
  • Frost pattern
  • Low side pressures
  • High side pressures
  1. No failure at all
  2. Leak or low charge
  3. Partial Restrictions
  4. Complete restrictions
  5. Over charge

Maintenance tips:

  • Ensure adequate air flow to the system
  • Clean ststem regularly to ensure proper heat extraction
