The Trane Voyager units have a small disc gas screen that can prevent the unit from running if it’s too dirty. Before replacing the inducer, gas valve, limit, or hot surface igniter on a Trane Voyager, it would be prudent to check the gas screen to make sure it isn’t clogged. If that screen’s holes get clogged with dirt, the furnace will start up and then shut off.

Jeff generally uses a bristle brush to get the dirt off the screen. Then, he makes sure to mount it back into the unit correctly. If you don’t mount it correctly or misplace it, you may end up getting a callback.

If the gas screen is rusty, then you’ll also want to check the heat exchanger for rusting or other forms of wear and damage.

Another thing to note is that it’s best to change the inducer motor gasket before it has a chance to wear away or break down.
