How to Troubleshoot Rheem 90 Plus?
The Rheem C90 Plus troubleshooting should be performed with the unit turned off. Remove the plug from the outlet, take off the control door, and shut off the gas control pressure switch before starting. After you’ve switched off the gas control switch, leave the house for 5 minutes to allow the gas in the supply lines to dissipate. You should not smell the gas. If you do, turn off the gas control switch and call the fire department immediately. Here are some tips you should try if you encounter a problem with your furnace:
There are a variety of issues that may arise with the operation of your heater. Prior to addressing any other concerns, you should verify that your heater is powered on, plugged into a power outlet, and working properly. If your heater is not receiving power, you should reset the circuit breaker if it has tripped off. If your circuit breaker is off, you should check for damaged wires that have turned black. A burnt-out fuse should also be replaced.
See if the thermostat’s setpoint is set at a higher temperature than normal. If it is, press the reset button twice. Also, check the thermostat’s batteries and replace them if necessary.
You should deactivate your furnace if it does not produce heat or an odorous gas when turned on. Immediately unplug the furnace from the power source and remove the control panel. Then, turn off the gas control switch and wait a moment. Remove the filter from the furnace’s front panel after shutting off the gas control switch. After cleaning the filters with a few drops of dishwashing liquid and water, rinse and air-dry them thoroughly before putting them in the Rheem furnace. Turn the switch back on and close the control panel. Finally, turn on the furnace’s power position.
If the igniter on the furnace isn’t working, you’ll need to relight the pilot. Make sure to dry up any water around the pilot light if it fails to light, as well as any water. You can examine the transformer with an insulated screwdriver to see if it’s working properly. When you touch one of the terminals with the screwdriver, you should also check the power arcs. If the current is low, you must replace the transformer. Any broken or corroded wires, as well as electrodes, must be changed. You must also check the pilot thermocouple and replace it if necessary.
Your Rheem C90 heating system may be overheating if you can feel the heat coming from the combustion chamber door. A buildup might heat proper ventilation if you notice the heat at the door. You should clean the exhaust pipe, chimney, and combustion chamber as well. If the heat exchanger and seals are broken, they should be replaced.
Certain rooms may be heated by the unit, so check the vents in your rooms for dirt. Broken exterior piping should be replaced. You should also clear obstructions from interior vents if any exist.
