When experiencing trouble with a Bryant furnace, it's easy to get assistance from a Bryant dealer or online at bryant.com. However, there are some things that can and should be done before calling the dealer.
First, ensure that the thermostat is set to the "heat" position. Check to see if there is power to the furnace by turning on the fan setting on the thermostat. Then, check to make sure that the temperature on the thermostat is set higher than the temperature inside the home.
Check the circuit breaker. The next step is to check to see if the SSU switch is in the "on" position. Also, determine if the filter has been changed recently and that nothing is blocking the return air grilles. If this does not work, contact someone at the Bryant company for assistance.
