Rheem classic 90 plus furnace. Two green lights on the panel (not blinking, solid), will not do anything. Thermostat clicks, indicating it should be turning heat on. No blower unless i manually turn t

Strange thing is, this issue is my upstairs attic unit. The down stairs unit is working just fine, it has same 2 green lights on the panel. Neither blinking, yellow, or red?

You will need to jump out the tstat to determine that the tstat is sending the signal to the furnace. Sounds like a thermostat problem.

How do i prime the water trap on a rheem classic 90


This trap will fill itself up when the furnace runs for the first time. It does not need to be primed to make it work. If you have the drain end above another p trapped drain.

I triped my breaker that controlled the unit and reset breaker but of the 2 green lights the one on the left is blinking unit power on but doesnt stay on for but a few miniutes please advise the unit...


Please don't try again and again. The breaker tripping is an indication of fault in your a/c.

Check indoor and out door for loose contacts.If anything, rectify. Check blower motor, fan motor and compressor for grounding. Check with an ohms meter, keep one end with any tewrminal and second with ground. If anything reading even 00.00, it's grounding. The particular spare/s to be replaced. Call repairman to check, if you're not aware of it. Thanks.

On occasion, my furnace will not kick on at


If your Rheem furnace is less than 10 years old, it may store an error code to help you figure out if it is the furnace or the thermostat. Look at the circuit board for a blinking light. If you have to remove the panel that opens up the door safety switch, it will erase the code. Look for a small viewing port. Next time the furnace fails, prior to doing all the things you did last time, look thru the viewing port to count the number of blinks. Once you get the number, open the cabinet and on the wiring diagram glued to the back of one of the panels'\; there will also be an error code chart. It may give you a starting point where to look. If you have no error code, chances are that your thermostat is freaking out or has a bad connection. Hope this helps.

My rheem cri II furnace will not work unless I turn the gas valve knob from on to off and back. The green led light is blinking then solid when I reset knob. Any ideas?


The green light is flashing an error code. When you turn the knob off and back on you are resetting the safety. Look for the number of blinks in a row. Then find the legend for codes on gas valve or on furnace. When is the last time you changed the air filter? A dirty filter can cause this problem.

Ruud achiever 90 plus blower not working


does the furnace ignite?? your system may not have been lighting and has gone into ignition lockout count the codes of the led lights then remove panel led diagnostic codes are listed there.
if led codes indicate no problem verify capacitor is good and that mtr is getting 115 volts.
