Air Conditioner Repair

Rheem manufactures appliances that homeowners have come to trust. Even a trustworthy appliance requires occasional maintenance or repair, however. If you’re in need of Rheem appliance repair from experienced professionals, your local Appliance Helper can help.

Rheem Air conditioner not cooling 
If the air filter is clogged, air cannot flow properly through the air conditioner. This greatly reduces the cooling capacity of the air conditioner. In addition, if the air filter is clogged, the evaporator coils will frost over. To remove debris from the air filter, try cleaning the filter. If it is not possible to clean the air filter, replace it. 

Rheem Air conditioner fan not working 
The dual shaft fan motor (or circulation fan motor) might be defective. The circulation fan motor has two fan blades: one on either side of the motor. On one side, the fan blade draws in outside air over the condensing coil to dissipate the heat. On the other side, the fan blade directs the air over the evaporator coil. The dual shaft fan motor has bearings that can loosen or bind over time. To determine if the motor bearings are defective, wiggle the motor shaft. If the motor shaft is loose, or if it won’t turn at all, replace the fan motor. 

Rheem Air conditioner compressor won't run 
The temperature control board provides voltage to the fan motor and compressor. If the control board is defective, it may stop providing voltage to the compressor. Control boards are often misdiagnosed. Before replacing the temperature control board, make sure you check more commonly defective parts—particularly the compressor overload, capacitor and the compressor itself. If you are certain that all of the other components are working properly, replace the temperature control board. 

Rheem Air conditioner won't turn off 
The condenser coils dissipate the heat as the refrigerant passes through the coils. If the condenser coils are dirty, they won’t be able to dissipate the heat as effectively. As debris builds up on the coils, the air conditioner will become less efficient, causing the air conditioner to work harder to cool down. If the coils are significantly dirty, the air conditioner will not be able to maintain the proper temperature, and the compressor will run continuously in an attempt to cool the room. Check the condenser coils to determine if they are dirty. If the condenser coils are dirty, clean them. 

Rheem Air conditioner is loud or noisy 
When the compressor is wearing out, it generates more noise than usual. When this happens, it is not necessary to replace the compressor—compressors often last for years after they become noisy. However, if you would prefer to have a new compressor, have a licensed professional replace it. 

Rheem Air conditioner remote control not working 
First, try replacing the batteries in the remote control. If installing fresh batteries doesn’t solve the problem and you can still operate the air conditioner manually, the remote control might be defective. If you think the remote control is defective, replace it.

Furnace Repair

Rheem manufactures appliances that homeowners have come to trust. Even a trustworthy appliance requires occasional maintenance or repair, however. If you’re in need of Rheem appliance repair from experienced professionals, your local Appliance Helper can help.

Rheem Furnace not heating 
The igniter gets very hot and glows bright orange to light the gas burner. If the igniter fails or cracks, the furnace won’t heat. To determine if the igniter is faulty, remove the igniter and inspect it for cracks. If the igniter is cracked, replace it. If the igniter is not cracked, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it. 

Rheem Furnace is noisy or loud 
The blower wheel blows air out of the furnace and through the house. The blower wheel is attached to the blower motor shaft with a set screw. If the set screw is loose, the blower wheel will wobble on the motor shaft, and the wheel will be noisy as it turns. Check the set screw to ensure that it is properly tightened. Next, inspect the wheel for damage. If the blower wheel is damaged, replace it. 

Rheem Furnace starts then stops 
The flame sensor monitors the burner to detect whether or not a flame is present. If the flame sensor is defective, it might fail to detect a flame. If the flame sensor does not detect a flame, the control board will shut off voltage to the gas valve to prevent the furnace from heating. Sometimes, if the flame sensor is dirty, it will fail to detect a flame. Try cleaning the flame sensor with a fine abrasive pad. If the furnace still doesn’t heat, replace the flame sensor. 

Rheem Furnace blower not running 
The blower motor blows air through the return vent, past the heat exchanger, and into the home’s venting. First, make sure that power is getting to the motor. If power is getting to the blower motor, but the motor does not run, the motor may be burned out. If the blower motor is burned out, replace it. If the blower motor hums, check the blower fan to ensure that it spins freely. If the blower fan is unobstructed but does not spin freely, replace the blower motor. 

Rheem Furnace blower runs all the time 
The control board has relays that regulate the voltage to each component in the furnace. If the relay that controls the blower motor fails while it is closed, it will send continuous voltage to the blower motor, causing the motor to run continuously. If the control board is at fault, replace it.

Water Heater Repair

Rheem manufactures appliances that homeowners have come to trust. Even a trustworthy appliance requires occasional maintenance or repair, however. If you’re in need of Rheem appliance repair from experienced professionals, your local Appliance Helper can help.

Not enough or no hot water from the heater 
1. Check your household’s water usage. If the usage exceeds the water heater’s capacity, wait for the water heater to fully recover. 
2. Check the water heater’s power supply. Check for blown fuses or a tripped circuit breaker. Ensure the disconnect switch, if used, is in the on position. 
3. If it is gas heater, check that the water heater is receiving fuel by ensuring that any cutoff valves in the gas line are turned to the on position. Have other gas water heater problems looked into and serviced by a qualified technician. 
4. Check the water heater thermostat for proper setting, and readjust the setting if needed. 
5. Ensure that all faucets are closed and are not leaking. 

Why is my Rheem water heater not heating? 
1. Your electric supply may be off and there is no power going to your water heater. You need to make sure electric supply to water heater and disconnect switch, if used, are in the ON position. 
2. Electric service to your home may be interrupted. Confirm whether your home and nearby homes have power. Contact the local electric utility if there is power interruption in your home. 
3. A fuse may be blown or a circuit breaker tripped. Check for blown fuses and tripped circuit breaker. Replace fuse if blown or reset circuit breaker to fix the problem. 
4. The temperature limiting control (ECO) could have broken the power circuit to the heating element after sensing excessively high water temperatures. To fix the problem, you must manually reset the ECO. 
5. The thermostat may be set too low. You can regulate the temperature of the water in the water heater by setting the temperature dial of the adjustable surface mounted thermostat located behind the jacket access panel. 
6. Leaking or open hot water faucets. Make sure all faucets are closed. 
7. During winter months, the cold water inlet temperature may be colder. This is normal. The cold water inlet takes longer to heat. 
8. If the issue doesn’t resolve after checking the above issues, there could be a problem with your wiring. Make sure power supply voltage agrees with your water heater rating plate. The branch circuit wire and fusing or circuit breaker should be of proper size. Also, make sure that the electrical connections are tight and the unit is properly grounded. Refer to installation instructions that came with your unit. 

Pilot light won’t  light or stay lit 
If the pilot light on your Rheem water heater won’t light or stay lit, it could be because of a blocked gas line. Other possible causes for this problem are a faulty thermocouple, malfunctioned gas valve, or something as minor as draft coming from a crack in the wall or under the door. 
1. Open the valve on the gas line by turning the handle until it is parallel to the gas pipe. Turn the gas control knob to the “Pilot” position and push it in. Can you hear a faint hissing sound? If not, there may be a blockage on the pilot supply tube, or the heater gas tube may be faulty. 
2. Turn off the gas, disconnect the pilot supply tube using a small wrench and clean it out with compressed air. If the problem persists, you may need to clean or replace the gas valve. 
3. Light the pilot if you hear a hissing sound when you depress the gas control valve. If the flame starts but goes out shortly, check for drafts. Inspect the vent if you can’t find the source of draft in the room. It should extend 18-24 inches above the roof line and be free from obstructions. Even a small breeze will blow the pilot if the vent is too short. 
4. If the flame stays lit while holding down the button but goes out when you release it, adjust the thermocouple. This is the small device, shaped like a bulb, located near the pilot aperture. Check to make sure the thermocouple isn’t loose and fell slightly out of position. 
5. Replace the thermocouple if adjusting it doesn’t fix the problem. Turn off the gas, then disconnect the thermocouple, pilot tube, burner gas supply and pilot igniter from the gas valve and remove the sealed access door. Install a new sealed access door after replacing the thermocouple to prevent carbon monoxide getting into your home. 
6. If the above steps don’t fix the problem, contact your gas or propane supplier to inspect your service lines. The gas could be contaminated by water or oil that is restricting the gas flow. 

Rheem water heater overheating 
1. Check the thermostat and adjust lower if necessary. Sometimes the dial is tweaked too high accidentally. 
2. In time, mineral settle around the heating element. When these heating elements get coated with sediment, they have to work harder to heat the water. This may lead to the elements overheating, which is why your water heater is suddenly hot. Check the heating elements for mineral scale build up. Remove and clean the heating elements if necessary. 
3. The pressure relief valve allows buildup steam to escape from inside the water heater. If this valve is blocked, your hot water will come out hotter than normal. If you can hear water boiling inside your water tank, you need to shut down the power to your heater immediately as this could cause an explosion. Call a qualified plumber to have it checked out after shutting off your water heater. 
4. If your water heater is still overheating even after adjusting the thermostat accordingly, the thermostat could be faulty. You need to replace the thermostat. 
5. If adjusting the dial on your gas water heater doesn’t fix the problem, replace the valve assembly.
