Refrigerator
The primary component that cools the refrigerator's interior is:
The evaporator, a system of coils or tubes that absorb heat from the air inside the appliance as a liquid refrigerant vaporizes. The compressor pressurizes the refrigerant, the expansion valve reduces its pressure to allow evaporation, and an evaporator fan circulates the cold air throughout the refrigerator and freezer compartments
How do you know if you can access a home without a resident present?
Work order will state PTE or permission to enter.
What prevents the dryer from overheating?
Thermal fuse
Which washer part controls the water level?
The water level pressure switch
What part heats the burners on an electric range?
Heating element
What common issues causes a fridge not to cool?
Dirty or blocked condenser coils, which prevent heat from escaping, or blocked air vents, which impede cold air circulation. Other common issues include faulty evaporator fans that circulate air
What safety feature prevents microwave leakage?
The mesh-covered door, which acts as a Faraday cage, and the safety interlock switches
How do you test if a dryer heating element works?
Continuity test with a multimeter
What sensor detects washer drum imbalance?
Load sensor
What causes a gas range burner not to light?
Clogged burner or faulty igniter
What refrigerant is commonly used today in refrigerators?
Modern domestic refrigerators commonly use R-600a (isobutane) or other hydrocarbon refrigerants for their low environmental impact, while R-134a was once prevalent and is still found in some units. Older systems used ozone-depleting R-22, which is now phased out.
What does the turntable in a microwave do?
Evenly distributes microwaves for uniform heating
What lint buildup issue affects dryer performance?
Lint buildup in a dryer's lint filter or vent system causes restricted airflow, which makes clothes take longer to dry, increases energy costs, puts strain on the dryer's components, and creates a significant fire hazard because lint is highly flammable
To prevent mold, odors, and mildew buildup, you should regularly clean out this washer component, especially on front-loading models
The detergent dispenser and door seal
What part controls the oven temperature?
Oven thermostat
What part helps maintain fridge temperature by cycling the compressor?
Thermostat
What feature prevents microwave operation when the door is open?
Safety interlock
What is a common cause of dryer overheating besides a blown thermal fuse?
is restricted airflow due to a clogged lint filter, blocked exhaust vent, or a damaged blower wheel
What is a common reason a dishwasher won’t drain?
Clog in the drain hose or pump
What type of gas is used in most gas ranges?
Natural gas or propane
What is the role of the evaporator coil in a refrigerator?
Absorbs heat from inside by vaporizing refrigerant or converting liquid refrigerant into a gas and thereby creating a cold environment for food storage.
What is an easy way to clean the microwave?
Fill a microwave safe bowl or cup with water and microwave it for about 5mins and then take out and microwave can easily be wiped out.
The drying time is not controlled by the amount of moisture removed; instead, it is controlled by:
The temperature of the air along with drying time.
What part drains water from the dishwasher?
Drain pump
The device that prevents a range or oven from tilting is called:
anti-tip bracket
