Rheem gas furnace blower unit not working properly

I have a Rheem gas furnace, model RGPN-10EAMER. The blower unit appears to work but air is not (noticeably) blowing from the ceiling air ducts. The burner unit is working fine. How do you adjust the blower speed to increase the air flow?

Look at circuit board and follow wires that come from fan motor, if this is a standard motor black is high and it will be going to a prong that says cool, red is low and it will go to heat, you will have a yellow and a blue that are "parked" remove red park it were the blue is and put blue on heat, if this is a variable speed motor you will have to set dip switches via your equipment manual

Where is the filter on a rheem corsair furnace?

I'm not familiar with the Rheem Corsair gas furnace, but the filter will be somewhere, filtering the return air. Is the furnace installed as an upflow, down flow or horizontal? Locate the blower door, open it up then work your way back on the duct that is returning air to the blower. Sometimes homes will have a filter return grill in a hallway ceiling. The grill has a couple nuts that can be removed, the grill swings down and houses the filter.

Why will the pilot light on my gas furnace not stay lit?

You have either a defective thermocouple or a faulty gas valve.
Look online for methods of checking the thermocouple
milli-volts reading with a multimeter. 15 or 20 Mv is the average.

Rheem rgph 10eamer 8 yrs old ...blower motor wont stop running...i had the a/c on....decided to ck the furnace ...switched to heat...blower still spark from direct spark...

Hi Richard. The switch they are talking about has a small tube coming from the induction blower housing straight to the switch. The best way to test it is to blow and **** on the tube while it is still connected to the switch. You should hear small clicking sounds coming from the switch, if not than it needs to be replaced. Another thing to try is a small wire or paperclip through the small opening where the tube came off. Sometimes this gets clogged and causes the same issue. Other than that, it can be a blocked flue or the inductive blower motor itself is not working properly. Hope this helps and good luck!

No heat and I'm cold.

Do you have the code reference on your furnace door? If so what does it say? The furnace has locked itself out, and we need to determine what in the world it needs..
