Question about Heating & Cooling

1 Answer

My furnace turns on and runs for a short time then shuts off. It will not bring the temperature to the thermos setting. I don't see a flame sensor any where?

Forgot to mention it is an approx. 20 year old Keeprite

    Flame sensor is a small rod sitting on the opposite side from ignitor. It is on the "flame" side of the gas tubes and usually to the far left or right, whichever is opposite your ignitor. Held in place by one 1/4 inch screw.

Fan comes on no heat


turn a/c power off. place a jumper wire between both sides of switch, leaving wire attached on both sides. power on, set thermo to heat, if furnace stay lit after test, replace rollout switch. If furnace shuts down after short time it's not the rollout. please remove jumper after test.

There are a few different reasons for short cycling of a furnace.
1. Inadequate air flow. Not enough air moving through the furnace can cause it to overheat and trip the high temperature limit switch.
check to see that all registers are open and returns are not blocked.
2 Improper heat anticipator setting on thermostat. Some thermostats have a heat anticipator and too low of a setting can cause short cycling.

4 Partially blocked drain hoses. If the condensate backs up into the furnace it can shut the flame off and then when the condensate drains the furnace starts again. Check all drain hoses to make sure they are clear.
These are just some of the possible reasons for short cycling .
Hope this helps.

Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor.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.

Furnace shuts down intermittently when calling for heat


The flame sensor is not working properly, it is not allowing the ignitor to ignite, and this is making the system shut down, the flame sensor has obtain a build up of carbon, you will need to remove the flame sensor, and take a little piece of sand paper to remove the black carbon from the flame sensor stem, clean until the stem is shinning, replace the flame sensor and turn the furnance back on this will correct the problem.

Ruud furnace Model URKA A030jK08 Code opt 589


Flip the lower panel over and look for a wiring diagram. On that diagram there will be a diagnostic chart. Let me know what 5 blinks represent. Then I want you to read on.

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).
