Due to the many different questions I see about Air Conditioning, I am including this overview to help us better understand each other for trouble shooting. A basic air conditioning system has a Thermostat, Air Handler or Furnace Fan and a Condensing unit. In a split system, the condensing unit (Condenser) is separate from the furnace and usually in the back yard. When working properly, it blows hot air. It connects to the cooling part of the system by 2 copper lines. One large line and 1 small line. The part that cools the house is the "Evaporator" and is usually on top of the furnace inside the square metal box (Plenum). When the Air Conditioner is running, the large copper line should be cold and the smaller line should be warm. Common signs of low refrigerant are that both lines are the same temperature and/or frost or ice has built up on the large line at the condenser. The thermostat will normally display room temperature on till it is touched to change the setting. It could have a "Span" setting as well as times and temperatures. The operating "span" of MOST residential thermostats is 40 to 90 degrees. That means you can set it as low as 40 degrees and no higher than 90 degrees. It probably has a fan switch also. When in the "ON" position, the fan will run constantly, 24 / 7, but the condenser will still cycle on and off as needed to keep the house at set point. If you have a suggestion to include in this paragraph, please let me know. Roger

There are service ports on the ends of the two copper lines at the condenser. Be VERY careful not to get any air in the system. Air carries moisure which will create acid and destroy the system. Don't touch the the smaller line. Pressure there is usually over 200 PSI. You sound like you have done this before. If not, let me know. Roger

I have a rheem classic quiet 80 . furnace starts up but the igniter will not kick in to start the flame


This problem can be one of two things:

1) Bad igniter.

2) Control board not sending 120 volts to igniter.

You will need a multimeter to verify if the igniter is receiving 120 volts.

Hi, I ahve a Rheem Classic Plus Series SUper Quiet 80 Unit and no air is blowing thru the vents but the inside/outside units kick on? can you help?


Is the inside fan running? If it is then check your air filter. If it isn't, turn off power to the inside unit and see if the fan turns freely by hand. Next check the capacitor for the indoor fan. Does the fan on this unit connect to a circuit board? Set the thermostat to make the air come on and check for power where the fast speed wire connects to the circuit board and neutral. If it's not there, the circuit board is probably bad. You can look at the back side of the board to see if any traces are burnt off. Let me know what you find.

I have a rheem classic series super quiet 80 furnace. when the panel that covers up the control board is removed is there a reset button or sequence that mut be performed so the system will once again run.


Hi,
no just repalce all the covers and then cycle to power to the unit and it should take off and go...be aware that the t-stat could take five minutes or so to recycle and star the unit also..
