The Legacy Line Plus 80 is a residential gas furnace manufactured by Bryant Products. The company was founded in 1904 by Charles Bryant, providing heating and cooling systems for homes. Today, Bryant provides a multitude of heating and air conditioning products for both residential and commercial environments. Bryant remains the brand name, though the Carrier Corporation is now the actual parent company and manufacturer. Serious repairs to a Legacy Line Plus 80 gas furnace should be conducted by a qualified service technician. Regular inspection and care of a Bryant furnace can help optimize its continued performance.

Check the thermostat heat setting position if the furnace fails to produce heat. The location and appearance of the thermostat controls will vary according to the model and manufacturer. Confirm that the thermostat heat setting position is in the “On” position.
Confirm that the temperature set on the thermostat exceeds the ambient room temperature if the furnace fails to produce heat. Both the temperature setting and ambient room temperature will be displayed on the thermostat, though the control panel appearance will vary depending on model and manufacturer.
Inspect the home circuit breaker panel if the furnace fails to turn on. Switch the circuit back on if the switch has been tripped due to an overload. A device may have to be unplugged or deactivated from the circuit if the furnace continues to overload the circuit breaker.
Replace the furnace filter if the furnace persistently overheats and shuts down. Turn off the power to the furnace. Remove the filter cabinet door on the side of the furnace — this may require the removal of a single thumbscrew. Remove the air filter, keeping the dirty side up to avoid making a mess. Inspect the filter for any tears or holes, and replace the damaged filter with a new one. If the filter type is disposable, replace the dirty filter. Clean a washable filter in the sink using a mild detergent. Rinse the filter thoroughly and let it air dry. Reinstall the filter once it has completely dried.
