Troubleshooting a Bryant Gas Furnace

If your gas furnace isn't performing as expected, here are few things Bryant recommends to check before calling for service.

1. Check to confirm your thermostat is set on "heat".
   
   
2. Make sure your thermostat's temperature setting is set higher than the indoor temperature shown on the thermostat.
   
   
3. Ensure that there is power to the furnace by turning the fan to "ON" by using the fan switch on the thermostat.
   
   
4. Check the circuit breakers at the electrical panel to see if one has tripped.
   
   
5. Check the SSU switch (it looks like a light switch on a gray box located at the furnace) to be sure it is in the “ON” position.
   
   
6. Check to ensure the furnace filter isn’t in need of replacement.
   
   

• All one-inch thick furnace filters should be replaced monthly.
  
  
• Wider two-inch thick and other high-capacity pleated filters can most likely be changed every other month or just six times per year.

  7.  If the system is running but you have not changed your filter, the filter needs to be replaced.

  8.  Check all return air grilles to make sure they are not blocked by furniture.

• Check all supply air registers to make sure they are open and blowing air. (The return air grilles are normally located on your walls and are wide and flat).
  
  

If this checklist does not solve your problem, contact us for service. Be sure to have your model number.

Where do you find the model number?

In addition to being listed in your owner’s manual or other paperwork that came with your Bryant product, the model number is also posted directly on your unit.

• Air Conditioners and Heat Pumps: You can find the model number listed on a “rating plate” sticker on the unit above the back-seated service valve connections.

• Gas or Oil Furnaces: Remove the front door and look at the upper-left side of the unit. You can find the model number listed on a “rating plate” sticker inside of the unit.
