Common Issues with Rheem Criterion II
Rheem Criterion II gas furnaces might encounter a few common issues. Understanding them can help you troubleshoot effectively.
Ignition Problems
Ignition problems prevent your furnace from firing up. Check the following:

Troubleshooting Steps
Follow these troubleshooting steps to address common issues with your Rheem Criterion II gas furnace effectively.
Safety Precautions
Before starting any troubleshooting, prioritize safety. Always turn off the furnace’s power supply to avoid electrical shock. If gas is involved, ensure appropriate ventilation. Keep flammable materials away from the unit. Wear gloves and safety goggles to protect yourself from debris or sharp edges. If you’re uncertain or uncomfortable, consult a professional technician.
- Check the Thermostat: Ensure the thermostat is set to ‘heat’ and the desired temperature is higher than the current room temperature. Replace the batteries if necessary.
- Inspect the Power Supply: Examine the furnace’s power switch and circuit breaker. Reset the breaker or switch off the power, then turn it back on to restore power.
- Examine the Gas Supply: Confirm that the gas valve is open and there are no gas leaks. If you detect a smell of gas, leave the area immediately and contact your gas provider.
- Inspect the Pilot Light: Check if the pilot light is lit. If it’s out, you can relight it per your furnace’s instructions, but if it won’t stay lit, the thermocouple may need replacement.
- Clear Air Filters: Dirty air filters restrict airflow. Inspect and replace or clean filters if they’re clogged.
- Check Vents and Ducts: Ensure all vents are open and unobstructed. Look for blockages in ducts that could hinder airflow.
- Examine Blower Motor: Confirm the blower motor operates correctly. Listen for unusual noises, and if the motor doesn’t run, check the capacitor and wiring.
- Look for Error Codes: Review the display panel for any error codes. Refer to the owner’s manual for code descriptions and suggested actions.
- Contact a Professional: If issues persist after these steps, obtaining a professional evaluation can provide further insight and repair options.
These steps can help resolve many issues and maintain the function and efficiency of your Rheem Criterion II gas furnace.
