I have a Rheem furnace, model RGDG 100AUER. Furnace & fan

This answer was rated:

I have a Rheem furnace, model RGDG 100AUER. Furnace & fan turns on, but there is no hot air being coming thru vents. It stays on for about 30 seconds.

M Oglesby :

Hello I am here to assist you.

M Oglesby :

What stays on for about 30 sec.? The burners or the Fan?

Customer:

the burners for sure...not sure if fan stays on for 30 seconds

M Oglesby :

This may be a flame sensor issue.

M Oglesby :

The flame sensor rod is a small thin steel rod that is straight or L shaped and is usually located near the pilot igniter or in the path of the burner jets. Locate it, remove it, and clean it with a piece of emery cloth or sandpaper very good.

Customer:

i cleaned it and that didn't help, i then rbought a new one and that didn't help

M Oglesby :

If you set the thermostat to the fan on position, do the fan come on?

Customer:

fan doesn't come on

M Oglesby :

That is your problem, either you have a bad fan motor or a bad fan capacitor.

M Oglesby :

The fan capacitor is located on or near the blower motor housing and resembles a oversized battery.

M Oglesby :

It is usually silver or black. Locate it and replace it.

M Oglesby :

If this does not correct the problem, then you have a bad fan motor. If the fan motor is bad, you will have to buy a new fan capacitor anyway so you may as well change the fan capacitor first.

M Oglesby :

If the Fan motor is bad, you will have to hire a technician to change it out.
