When Heat Not Coming from Trane Gas Furnace

If your furnace does not produce heat from vents when it turn on, it's not a difficult problem. Usually, if your gas furnace doesn't blow hot air, it means that there is a problem with your gas. Your device can't heat the air without supplying energy. Hence, you have to check whether the gas is connected and flowing correctly or not. If not, correct it.

Trane Furnace Ignitor Problems

If your furnace ignitor is igniting, follow the below things to fix the problem.

Check if there is a problem with the circuit breakers. Inspect your circuit panel to see whether switches are switched on.

Examine the drain pan.

All times it may not because of the ignitor itself. Sometimes there is standing water in the drain pan of your Trane furnace. Then, your system will not run to prevent the risk of overflowing nothing but the ignitor won't work. Clean the pump. If it doesn't help, you need to replace the pump assembly.

Check for the clogged air filter.

To prevent the ignitor type of problems, you should change the air filter regularly. When the air filter is clogged, the furnace will no longer ignite. So, it's the best way to check the air filter when your ignitor not working.  

Inspect the Gas Supply

When there is a problem with your gas supply, it causes your furnace ignitor to fail to ignite. If no problem is found with your home's gas supply, then consider that there could be an issue with the gas supply to your Trane furnace. Contact an expert to fix the issue.

Check the Ignitor Sensor

The ignitor sensor intimates the furnace when it is safe to ignite. When this sensor senses a flame, it tells the device that it is safe to turn on the gas supply. However, sometimes, it can become dirty and unable to sense the flame. Then, it needs to be cleaned.

Additionally, you need to remember the age of ignitor. Normally, ignitor in the furnace will not work as long as the furnace. Over time, the ignitor will start to lose functionality. You have to change the ignitor if needed.
