Furnace runs all the time

I have a RUUD Achieve 90 plus furnace, it seems to keep a good temp in the house. When it is cold out (10 to -0) it seems like it runs all the time. The furnace will shut off, then 2 minutes later it comes back on. The temp is maintained well . The is wife is freak'in out about it running all the time. Is it normal to operate like this?

Aren't they just lovely to mess with! I personaly don't think there suppose to run like that either. Mine did the same damn thing, run for awhile and "poof" back on again in about 2 minutes. Over and over!! All the time. What I did was mess around with the Thermostat. One of those old round ones. Looked like it wasn't Level at all, so I fixed that. Plus on the lnside of the thermostat, there's a little brass pointer (on the righside bottom) there's also a bunch of numbers on there which I have no idea what there for. Some of the numbers on it are: .8 .7 .6 .5 .4 .3 and so on. I'm trying to find out what their for and which one it's suppose to be pointed too. My sister was having problems with her furnace. It's a natural gas furnace. The maintenance man found a few things wrong with it. The air filter was (dirty) replaced. Replaced the Thermostat. Something in the furnace wasn't working right either. Not sure if it was the Igniter or the Jets? inside or not. Maybe it was both. I'd ask her but some women don't pay attention to things like that. lol
Hope this helps out. Good luck!

I am installing an Emerson programmable thermostat. We have a Ruud furnace achiever 90 plus that was installed 14 years ago. The thermostat mentions a power stealing switch.


The Ruud furnace is probably compatible. Power stealing is a way to recharge the thermostat battery from the 24vac control voltage used to operate the furnace. If you install the Thermostat in the "separate power supply mode" it does not need to power steal ever and will be much more reliable. Some thermostats don't get enough power in the power steal mode to keep the battery reliably recharged, especially during the cold winter months because the poiwer available to "power steal" is highest when the furnace is NOT running. You will need a separate 24 vac transformer and some wire.

I have a Ruud Achiever 90 Plus Gas Furnace with Air Conditioner. I have a new Nest Thermostat. What is the correct wiring connections on the Furnace?


A Ruud Achiever gas furnace I believe came in a two stage model for heating. What this means is that you will have a high and a low setting. Your furnace should have two wires that control the heating cycle a W1 and W2. This should correspond with the terminals on the nest thermostat. You may run into issues if you do not have enough thermostat wires to control the furnace. If you are ever in the need for Ruud And Rheem Gas Furnaces we offer a great selection online. Shop Natural Gas Furnace. We also have a chat line which can provide technical support.

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.

Where is the re-ignite switch on a RUUD achiever 90 plus furnace?


Te flame symbol on the T-stat is just telling you that the T-stat is calling for heat.

What you need to do is go to the furnace and see if there is a blinking light. If there is count the blinks and look for a blink code list on the wiring diagram.(Usually found on the main panel.)

After you have done that, disconnect power to the unit, and then reconnect after a few minutes. This will reset any auto switches if they are tripped.

Chances are the problem will occur again even if the furnace does fire back up, but it "may" get you through the night until you can either diagnose the problem or get a service tech in.

Ideally, have someone else turn the power back on, and the thermostat, while you are watching the furnace to see exactly what is happening.

If it does not operate properly at that time, let me know exactly what it is/is not doing and we can go from there.
