What kind of temperature controls are used in refrigeration?
What kind of temperature controls are used in refrigeration?
There are two types of temperature controls used in commercial refrigeration: 1. Thermostatic (either an air sensing type or evaporator coil sensing type) 2. Low pressure control Let’s start with thermostatic type controls.
What happens if you change the temperature of the evaporator?
It senses the temperature of the evaporator coil rather than air temperature. These two controls are not interchangeable. If you put an air sensing control in place of an evaporative sensing control, the evaporator unit will shut off permanently, causing the temperature to rise.
What happens if the thermostat fails in the closed position?
If the thermostat fails in the closed position, the unit will run all the time. Running constantly will cause the evaporator to freeze up, restricting the airflow and causing the temperature to rise. Use the same procedure described above to test the unit and replace the thermostat if necessary.
What to do if your refrigeration thermostat freezes?
If the evaporator continues to freeze up after the thermostat replacement, call a service company as you may have other problems requiring a trained technician. The other type of control is a low-pressure control . These are usually located in the compressor compartment.
What to do if your temperature control board is faulty?
If the temperature control board is faulty, replace it with the manufacturer-approved replacement part for your model. Use this procedure to replace the temperature control board in Kenmore, GE, Maytag, Amana, Frigidaire, Electrolux, Whirlpool and Haier refrigerators. 01.
How to replace the Cold control on a refrigerator?
Pull the control dial from the temperature control. If your refrigerator has a temperature control for the freezer next to the refrigerator temperature control, pull the dial from the freezer control as well. Always On. Always Open. 100% Digital. Lock Your Mortgage Rates On Your Schedule.
When is food safe with time and temperature control?
Keep food safe with time and temperature control. TCS foods are time and temperature abused any time they’re in the temperature danger zone, 41 to 140 degrees F. This occurs when food is: Not cooked to the recommended minimum internal temperature. Not held at the proper temperature.
How to replace a temperature control board on a refrigerator?
Pull the refrigerator away from the wall so you can access the water line connection and have room to work behind the refrigerator. Place a towel under the water valve assembly to catch water. Loosen the nut on the supply water line until the water line is free.
