Ruud furnace 2 blinking green light

It sounds like it starts up and runs for a minute or 2 and then shuts off for a few minutes then turns on for a minute or 2 and then shuts off again. This happens over and over again.

The ventpipe heat limit, fan limit, and chamber limits are only a few of the safeties that turn a furnace off when something is getting too hot. I recommend a qualified technician have a look at it.

SOURCE: "Cool" mode shuts off

An E1 error is automatically generated after the AC runs for so many hours to remind you to clean the filter. The owners manual says to clean the filter and unplug the unit, then plug unit back in and code will be reset. However, a User review stated that his code was not reset until he followed a fairly simple routine. "Unplug the unit. Hold down the power button and plug back in. Wait to hear a "beep" and then unplug it again. Plug unit in again and it should restart without E1 code."

SOURCE: Ruud Furnace won't turn on

Take of the access panel on the furnace and look for a wiring diagram either on the back of the panel or inside the housing. There will be a diagnostic chart on it that will give you a hint what 2 flashes mean. I think it is a "no Ignition" code. If it is, with the access panel off and the door switch taped in the closed position, the furnace will try to start if the thermostat is calling. You want to look at the control module to see if it is flashing, then you should notice a small fan that pushes out the combustion products start to turn. Then if you look in a small view port, you should see an orange glow followed by a clicking noise at the gas valve. Then you should notice a blue flame in the view port. This flame must stay on for 5-6 seconds or the unit will turn it self off. If one of these do not happen, you will need a technician to troubleshoot it. Check to see if all wires and hoses are tight and in place. Make sure your condensate hoses are not blocked and free of water. Make sure there is no blockage in your vent pipe(s).

SOURCE: 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.

SOURCE: unit starts and stops to often

No this is not normal. You have a problem refered to as "short cycling". This is an indication of low refrigerant charge. You need to have the unit leak checked, repaired and recharged,

Ruud 90+ Model UGRA 10EZAJS Trips Out


Check for condensation buildup in the Induction Blower housing. The condensate tubes or canister may be blocked and causing the diaphragm switch to trip the unit out causing the burners to shut down.

Sounds like the fan limit was not replaced correctly. You can try switching the blower to the On position (instead of Auto), if the furnace runs properly with the blower on that would be the most likely culprit.

Hi,
It appears to be the fan limiter switch. It comes on at a certain temp when heating up and shuts off on the high end of its setting. Once the burners are shut down, the fan continues for a few minutes to cool down the burners. The limiter switch is adjustable but it sounds to me to be defective and should be replaced. Good luck and stay warm, :-)

Hello, sounds like the limit switch is opening on the furnace.Usually when a furnace goes off on its high limit is becuase the airflow is being restricted making the furnace overheat. a limit switch is there to protect the furnaace from overheating, most cuases are either dirt or the blower motor not running up to speed, anything that cuts down on the airflow will cause the high limt switch to open.

If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

My furnace comes on and heates the house for about


There is a limit switch that is likely opening. Be sure your filters are clean and all registers and grilles are open and not obstructed. If the problem continues, you may have a dirty indoor coil or undersized duct work. Some models have a window where you can observe the LED lights. If when the furnace shuts down you see any blinking, you need to count the flashes and we can figure out what the problem is from there.

Ruud achiever 90 plus furnace will not start with door on.


I would try to check your return air first, making sure there is no blockage and that your air filters are clean. It almost sounds like when you take the cover off, you are pulling enough air into the system for it to run, but as soon as you close it off, it's not getting enough air flow, therefore, tripping a limit switch inside the furnace. Most furnaces will also have the codes for the flashing lights and what they mean on the inside of the door covers.
