16.
When charging, vapor should be added to the ____ side of the compressor.
Correct Answer
B. Low
Explanation
When charging, vapor should be added to the low side of the compressor. This is because the low side is where the refrigerant enters the compressor in its gaseous state. By adding vapor to the low side, it helps to maintain the proper pressure and temperature balance within the system, allowing for efficient and effective operation of the compressor.
17.
R-134A is a drop in replacement for R-12.
Correct Answer
B. False
Explanation
R-134A is not a drop-in replacement for R-12. While both are refrigerants used in air conditioning systems, they have different chemical compositions and properties. R-134A was introduced as a more environmentally friendly alternative to R-12, which is a chlorofluorocarbon (CFC) and has been phased out due to its harmful effects on the ozone layer. Therefore, in order to switch from R-12 to R-134A, modifications to the system are required.

Correct Answer
B. Too allow the freon to be saved while servicing the unit
Explanation
Shutoff valves on the compressor are installed and used during servicing to allow the freon to be saved. By shutting off the valves, the flow of freon can be stopped, preventing any leaks or loss of the refrigerant. This allows for efficient servicing and maintenance of the unit without wasting the freon.
25.
The pilot light on a standing pilot water heater won't stay lit. What might be causing the problem?
Correct Answer
B. The thermocouple
Explanation
The thermocouple is a device that senses the presence of a flame in the pilot light. If the thermocouple is faulty or not positioned correctly, it may not be able to detect the flame, causing it to shut off the gas supply to the pilot light. This would result in the pilot light not staying lit. Therefore, the thermocouple is likely causing the problem.

C. Turn off the main line breaker
Explanation
The first thing you should do when working on a defective breaker is to turn off the main line breaker. This is important to ensure that there is no power running through the breaker and to prevent any potential electrical hazards. Removing the breaker or shutting it off alone may not be sufficient to guarantee safety, as there could still be live electrical currents present in the system. Therefore, turning off the main line breaker is the correct and safest course of action.
30.
What is the purpose of a cap (capillary) tube?
Correct Answer
A. Too meter refrigerant of the evaporator
Explanation
The purpose of a capillary tube is to meter the refrigerant flow to the evaporator. It acts as a restriction in the refrigerant system, allowing only a certain amount of refrigerant to pass through at a time. This helps to regulate the flow and ensure that the evaporator is receiving the correct amount of refrigerant for efficient cooling.
31.
In roofing, a square (measurement) is an area of:
Correct Answer
B. 10 ft x 10 ft
Explanation
A square in roofing measurement refers to an area of 10 ft x 10 ft. This means that a square is a measurement unit used to quantify the area of a roof, with each square representing 100 square feet. This measurement is commonly used in the roofing industry to estimate the amount of materials needed for a roofing project.
32.
How many 4 inch x 4 inch ceramic tiles would it take to cover a 120 square foot area?
Correct Answer
C. 1080
Explanation
To find the number of tiles needed to cover a 120 square foot area, we need to convert the area to square inches. Since there are 12 inches in a foot, the area in square inches would be 120 * 12 * 12 = 17,280 square inches. Each tile is 4 inches by 4 inches, so the area of one tile is 4 * 4 = 16 square inches. To cover the entire area, we would need 17,280 / 16 = 1,080 tiles. Therefore, the correct answer is 1080.
33.
Algae are microscopic plant life.
Correct Answer
A. True
Explanation
Algae are microscopic plant life because they are photosynthetic organisms that can produce their own food using sunlight, carbon dioxide, and water, just like other plants. They are typically found in aquatic environments, ranging from freshwater to marine habitats. Algae can be single-celled or multicellular and come in various shapes and sizes.

This can result in the oven becoming too hot or not reaching the desired temperature.
36.
Which of the following would NOT cause a toilet to continually run?
Correct Answer
B. Broken flapper chain
Explanation
A broken flapper chain would not cause a toilet to continually run because the flapper chain is responsible for lifting the flapper valve to allow water to flow into the toilet bowl. If the chain is broken, the flapper valve would not be able to lift properly, resulting in the toilet not flushing at all rather than running continuously.
37.
If a dishwasher hums, but the motor will not run, the probable cause is:
Correct Answer
B. The seal is frozen
Explanation
If a dishwasher hums but the motor will not run, the probable cause is that the seal is frozen. When the seal is frozen, it prevents the motor from running properly. This can happen due to a buildup of ice or frost around the seal, which restricts its movement. This issue can be resolved by thawing the seal and ensuring that it is clean and free from any obstructions.
38.
Muriatic acid is used to ____ the pH level in a pool.
Correct Answer
B. Lower
Explanation
Muriatic acid is a strong acid that is commonly used in pools to lower the pH level. When the pH level of a pool is too high, it can lead to several problems such as reduced effectiveness of chlorine, cloudy water, and skin and eye irritation. By adding muriatic acid to the pool, it helps to neutralize the alkalinity and lower the pH level, creating a more balanced and comfortable swimming environment. Therefore, the correct answer is "Lower".

46.
An iced up evaporator is usually a sign of insufficient air through the evaporator coils or:
Correct Answer
A. Low charge
Explanation
An iced up evaporator is usually a sign of low charge. When there is insufficient refrigerant in the system, the evaporator coils do not receive enough refrigerant to properly absorb heat from the air. As a result, the temperature of the evaporator coils drops below freezing, causing moisture in the air to freeze and form ice on the coils. This can lead to reduced cooling efficiency and potentially damage the compressor if not addressed.
47.
What kind of head pressure would you experience if the condenser fan motor became inoperative?
Correct Answer
C. Very High
Explanation
If the condenser fan motor becomes inoperative, it means that the fan is not functioning to remove heat from the condenser. This would result in a buildup of heat and pressure in the condenser. Without the fan to dissipate the heat, the head pressure in the system would increase significantly, leading to a very high head pressure.
48.
A resident calls and complains that soap bubbles run out of the dishwasher when she runs it. A probable cause is:
Correct Answer
B. The resident used hand dishwashing soap instead of automatic dishwashing soap
Explanation
The most probable cause for soap bubbles running out of the dishwasher is that the resident used hand dishwashing soap instead of automatic dishwashing soap. Hand dishwashing soap creates more suds and is not designed for use in dishwashers, which can lead to excessive sudsing and overflow. The other options, such as a clogged drain or the dishwasher being too full, can also cause issues, but using the wrong type of soap is the most likely cause in this scenario.
49.
When should a pool filter be backwashed?
Correct Answer
C. According to the pressure
Explanation
A pool filter should be backwashed according to the pressure because backwashing is a process used to clean the filter by reversing the flow of water and flushing out any trapped debris. When the pressure in the filter reaches a certain level, it indicates that the filter is becoming clogged and needs to be backwashed to maintain proper filtration. Backwashing on a regular basis helps to keep the pool water clean and clear.
50.
What is the purpose of a breaker in an electrical circuit?
Correct Answer
B. Overload protection
Explanation
A breaker in an electrical circuit serves the purpose of providing overload protection. It is designed to automatically disconnect the circuit when there is an excessive amount of current flowing through it, preventing damage to the circuit and potential hazards such as overheating, fires, or electrical shocks. By tripping the breaker, it interrupts the flow of electricity, ensuring the safety of the circuit and the connected devices.
