If your Bryant gas furnace appears to be malfunctioning, there are some simple steps you can take to try to get it up and running again. Try these procedures first before you call a heating repair professional. His services won’t come cheap even if he can solve your problem in three minutes, so use these troubleshooting tips to try to solve matters yourself, first.
1) Double check that your Bryant furnace is getting power. Since electrical connections may not be visible depending on your installation, try setting the fan switch to the “on” position and listening to see if the internal fan switches on.
2) If the fan doesn’t switch on, check your circuit breakers to be sure that the one directing power to the furnace is in the “on” position.
3) The problem might be that your furnace has been inadvertently switched off, so find the thermostat on your Bryant furnace and make sure it’s set to the “on” or “heat” position.
4) Even if your furnace is on, someone might have changed the thermostat settings to a very low degree of temperature. Check the temperature setting on the thermostat yourself and make sure that it is set to a temperature higher than the current indoor air temperature. Otherwise, the furnace will never begin to produce heat.
5) The problem might be with air conveyance instead of power or settings. Therefore, check the furnace filter to see if it needs replacing. Recommended replacement schedules are six times per year, but monthly if the filter is only one inch thick.
6) Another air return issue could be that air return grilles have been accidentally blocked by furniture or other items such as luggage that has been set down. Take a tour of your house and examine all the registers to make sure they are free from obstructions. If you aren’t sure where to locate the grilles or registers, look along your walls at a height level of one foot or below. In some homes, particularly in manufactured housing, the registers may be located in the floor right alongside walls. Each room will normally have at least one air register for the heating system. Bathrooms are included in this figure, but closets generally do not have air grilles.
7) Even if air registers are not physically blocked by other objects, they might be in the closed position. Examine each one to be sure it’s in the fully opened position to allow a maximum level of air to flow through the Bryant furnace system.
8) In older furnaces, it’s a good idea to check that the pilot light for the unit is lit. However, if your furnace is less than ten years old, it will likely have an electronic ignition system rather than a pilot light.
If you try everything listed above and you still can’t get your Bryant gas furnace to blow air or produce heat, you will most likely need to consult an HVAC repair service. They can provide solutions that go far beyond the troubleshooting tips provided here.
