DIY Trane Furnace Troubleshooting

Finding a problem with a Trane furnace unit can feel like a nightmare to most customers, as trying to perform any Trane furnace troubleshooting can be like trying to understand a foreign language.

The manuals and explanations online speak in Trane language and often cannot be understood by the average customer.

The first and most important step in troubleshooting a furnace problem is finding out exactly what the problem is. This is usually one of the hardest steps as there are so many different things that could be wrong.

Some Trane furnace troubleshooting tips for identifying the problem include writing down all the issues the unit is having. Is the unit noisy? Is it leaking? Is it not heating or simply not working?

Once the problem is identified there are many online sources available to identify why the problem exists and how to fix it. Much of the time, a customer may be able to repair the problem without spending money on a repairman.

Some customers are not comfortable with or proficient in internet searches. If that is the case, take a trip to a local store that sells Trane models.

Chances are there will be a nice young lad or elderly employee that will be more than happy to help figure out what the problem is. Most hardware stores have unit manuals available, and more importantly, employees who understand how to interpret these manuals.

Once the customer has identified the problem and located help, whether online or at a hardware store, they can begin the daunting task of fixing the furnace. The most common problems are usually the easiest to fix.

A noisy furnace is usually caused by a loose access door or a worn out belt. Simply correctly fasten the access door or replace the belt. If the belt is sticking, there is a fan belt dressing available.

Spray it on the sticky belt and it should loosen up. If this still have not solved the noise problem, check if the belt is too loose or too tight and adjust accordingly. If all else fails, lubricate the motor and blower using motor oil.

If the blower is not operating, there are two very common problems. The blower control could be wrongly set, which is fixed by simply resetting the thermostat. If this does not work, the relays may be faulty, and unfortunately requires the help of a professional.

If the furnace continually turns on and off or is not producing enough heat, there are some easy fixes. Make sure the motor and blower are lubricated, clean or replace the filter, and make certain the blower is not clogged.

For insufficient heat, before trying all these troubleshooting tips, make sure the thermostat is set at the correct temperature.

If the furnace completely stops working, the first logical step is to check the power source. Is the furnace powered off or has the house lost power for some reason? Did a circuit breaker trip?

If the power and fuses all seem to be in working order, the motor may be overloaded. Wait about an hour and reset the furnace.

If after performing these basic troubleshooting tips, the furnace is still not functioning correctly, it is best to call a professional.
