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). 

 

Let us know what you found.

SOURCE: i have a Ruud Achiever 90 plus furnace that will not ignite

coming from the induced draft motor is an orange or gray rubber tube leading to a switch pull the end off that is connected to motor and poke a wire or something to insure the hole is not blocked if it is not replace the hose. next step is to check the switch make sure if possible try to jumper 2 wires and turn unit back on if it works then either switch is bad or vent piping is blocked.. For your extreme Safety, Please Do Use Furnace in this condition until problem is fixed. thanks glad i could help

SOURCE: My Ruud Achiever 90 Plus not blowing cooled air

Look on the condensor, (outdoor unit) at the very bottom of the rear panel and you should find a red reset button. push it. If that does not solve the problem, and the outdoor unit is running (make sure both the fan AND the compressor are running) then you are looking at a low refridgerant issue and possibly dirty coils.

In that case, clean the coils and have refridgerant added.

SOURCE: 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.

A sampling of various failure codes on a furnace:

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.

Furnace cuts off before reaching set temp.


You can make sure it is not the thermostat by crossing or jumping the R and W terminals (or associated wires) together. This will keep the furnace calling for heat. As it is approaching set temperature, get in front of the furnace and inspect the air filter to make sure it is clean, watch the control module for any error codes that may be turning off the system prematurely.

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Central heat not working right


You may just have a dirty air filter or your furnace may be flashing an error code that could help you. Look for a small viewing port that looks into the cabinet of the furnace. Look for a blinking light. Count the blinks and then find the wiring diagram pasted to one of the panels. On the diagram it will have a diagnostic chart where you can look up the error code. Read on for some basic info that may help you.

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model.

Will not heat up a room no matter how high i turn the temperature. I ve tried different modes overrides etc... nothing makes the heat just turn on.


If you are referring to the thermostat, try jumping the R and W wires together. If it starts, replace the thermostat. If not, go to the furnace and jump the R and W terminals on the circuit board. You may need to tape the door safety switch closed. If it starts, you have a bad thermostat wire. If not, check out the sequence of operation as below.
