Your Nordyne HVAC system consists of a complex set of machinery that can be subject to a number of problems, requiring you to pull out the toolbox and make repairs. Things such as faulty gas jets, burnt-out igniters and fried control boards are just a few of the problems that can affect your Nordyne furnace or heat pump.
Luckily, some of the problems are more common than others and are fairly simple to diagnose. Find replacement parts at Sears PartsDirect.

Everyday problems that can afflict your HVAC system
- A very common problem with furnaces is that they put out limited amounts of heat. This can be caused by a clogged air filter. Finding the correct intervals between filter changes will vary depending on factors such as pets or smokers in the household as well as the outdoor environment.
- A malfunctioning thermostat can cause a few different problems with your furnace. Either your furnace won't turn on or off, or it won't run at the temperature you designate.
- A noisy furnace can mean that the blower motor has come loose or has worn parts grinding against each other.
- Heat pumps have compressors that can become strained from being overworked because of weather conditions or the air intake being clogged. An overworked compressor is likely to experience a catastrophic failure and need replacing.
- Heaters use electricity to power heating coils that heat the oil inside of them. If these coils become damaged or deteriorate over time, then not only will they malfunction, but they'll also become a fire hazard.
How to replace the blower motor in your furnace
The first step to removing a defective blower motor is to shut off furnace power at the circuit breakers. Next, remove the panel to gain access to the blower. Write down the wire color configuration so that you won't crosswire the new motor by accident. Disconnect the motor wires and remove the mounting hardware to free the blower assembly and then remove it from the furnace. With the assembly removed, the next step is to remove the motor from the assembly. Start by loosening the set screw holding the wheel to the motor. Next, loosen the bolts holding the motor in place, and the motor should slide out of the assembly. Install the new blower motor and reassemble the furnace. Reset the circuit breakers to restore power to the furnace.
