Durastar Furnaces Troubleshooting: The Ultimate Guide

Durastar furnaces are known for their durability and reliability. However, just like any other machine, they will occasionally experience issues. When your Durastar furnace isn’t working properly, you need to know what to do so the issue doesn’t escalate into a bigger problem. Our troubleshooting guide will help you get your Durastar furnace back up and running in no time. If you can’t resolve the issue after following these instructions, contact a local service company that specializes in Durastar furnaces and has access to parts and service manuals specific to your model. They will be able to provide you with further troubleshooting steps as well as recommend appropriate maintenance procedures so this doesn’t happen again.

Check the Furnace Startup Timer

If your Durastar furnace isn’t heating, the first thing to check is the furnace startup timer. If the furnace was working fine but hasn’t fired up since there’s a good chance that the furnace startup timer has tripped. If the furnace startup timer is tripped, reset it by pulling the knob out and rotating it back towards the “ON” position. If the timer knob doesn’t budge, you will need to reset the furnace with a different method. If the furnace was shut down manually from the control panel, you can reset the timer by pressing the “OFF” and “ON” buttons simultaneously for 5 seconds. If the furnace was shut down by a power outage, reset the timer by pressing the “OFF” and “ON” buttons simultaneously for 15 seconds. You will know the timer has been reset when the display lights up.

Check the Electronic Control Module (ECM)

If the furnace isn’t heating, the next thing to check is the electronic control module (ECM). The furnace won’t fire up if the ECM isn’t sending a signal to the burners, so the control module may have failed. If the control module is faulty, you will need to order a new one and have an HVAC technician install it for you. Before the technician arrives, prepare by shutting off the power to the furnace and disconnecting the wires from the control module.

Check the Burners

If your Durastar furnace isn’t producing heat, one of the burners might be clogged. A dirty burner will reduce the furnace’s capacity and efficiency, which is why you need to clean the burners regularly. If one or more burners are clogged, you will need to replace them. Before you do, carefully inspect the rest of the burners to make sure they aren’t clogged as well. If they are, you will need to clean them as well. You can clean the burners using a wire brush or a cloth with a cleaning solution. Once you’ve finished cleaning the burners, ensure they rotate freely and that no obstructions are preventing them from closing completely.

Check the Air Filters

Since the furnace won’t be able to heat the house if the air filters are clogged, it’s a good idea to check them regularly. If at least one of the air filters is clogged, clean or replace the filter according to the filter’s instructions. If you have multiple Durastar furnaces installed in your home, check all of their air filters to make sure they aren’t clogged either.

Check the Ductwork

The Durastar furnace draws warm air from the ductwork and blows it into your house. If there is an obstruction in the ductwork, warm air won’t be able to flow properly. If there is a blockage in your ductwork, the Durastar furnace will significantly struggle to heat your house. To check the ductwork, you will need to open up the floorboards where the ductwork is running. Start by looking for the furnace filter, which should be located near the furnace. If you find an obstruction in the ductwork, there are a few ways you can remove it. You can try to dislodge it by tapping the ductwork with a hammer and sweeping the ductwork with a broom. You can also hire an HVAC technician to remove the obstruction.

Durastar Furnace Blower Doesn’t Run

If the Durastar furnace is heating but the blower isn’t running, the furnace is probably tripping the circuit breaker. Blowers don’t trip the circuit breaker unless they aren’t receiving the signal to run from the fan controller, which indicates that it’s not functioning properly. To check the fan controller, pull the knob out and rotate it to the “ON” position. If the blower starts running, you will need to replace the fan controller. If the blower doesn’t start running, the circuit breaker needs to be reset. If the furnace was shut down manually from the control panel, you can reset the circuit breaker by pressing the “OFF” and “ON” buttons simultaneously for 5 seconds. If the furnace was shut down by a power outage, reset the circuit breaker by pressing the “OFF” and “ON” buttons simultaneously for 15 seconds. You will know the circuit breaker has been reset when the display lights up.

Durastar Furnace Heating Issue

If your Durastar furnace is heating but you feel that it’s not hot enough, the air filter might be clogged. If at least one of the air filters is clogged, warm air won’t be able to flow properly through the system. If the air filters are clogged, clean or replace them according to the filter’s instructions. If changing the filters doesn’t solve the issue, the furnace blower might be clogged. Blowers generally don’t need to be maintained, but clogs are possible if you have pets or children. Blowers can clog if they aren’t receiving enough ventilation. Make sure that there’s enough room for air to flow freely around the furnace and that no obstructions are blocking the blower.

Durastar Furnace Won’t Turn Off

If your Durastar furnace won’t turn off, it could be caused by a faulty circuit breaker. To check the circuit breaker, pull the knob out and rotate it to the “OFF” position. If the circuit breaker is tripped, reset it by pressing the “OFF” and “ON” buttons simultaneously for 5 seconds. If the circuit breaker isn’t tripped, there might be a fault with the furnace’s built-in circuit breaker. You will need to call a technician to replace the circuit breaker.

Conclusion

The Durastar furnace is a durable, reliable furnace that will provide you with years of service. Unfortunately, it does have its occasional issues like any other machine. If your Durastar furnace isn’t operating as it should, follow our troubleshooting guide. If the issue isn’t resolved, you will need to call a technician for assistance.
