This sounds like an issue with the control wiring, there could be wires shorted togeher either at the thermostat, or in the wall, you need to isolate the wires at both ends then check for continuity with an ohmmeter there should be none) to verify which wires are shorted

Gas pack heater sporadic


Is this a package unit?

I have a RUUD gas pack unit.....when you turn on the heat, the blower does not blow any air out of the vents while on "auto". If you put it on "on" it blows cold air out of the vents. What is wrong?


Sounds like the thermostat is hooked up wrong. If the ac doesnt work right its in the thermostat programming or the wiring. Hope this helps good luck

Boiler keeps blowing fuses in pcb ideal isar he 30


The model # you listed is for a vent-free, natural gas, space heater and requires no electricity to operate. Unless, you have the optional blower. If the blower accessory is what's blowing the fuses, there is a short in wiring to the blower motor. Other than that, there is nothing else about this heater, that would be blowing fuses.

Is the above, the problem you're having? If so, unplug the blower from the wall outlet, until it can be repaired or replaced. The heater will continue to operate and heat with out the blower.

For more information about your heater, go to the link below.

Ruud Silhouette II Gas Furnace, purges, lights burners and burns until the blower starts and then burner stops and does not really blow very warm air. Once blower shuts off, it starts the process all over...


I would be looking at the heat exchanger. They are designed to have the heat from burnt fuel flow thru them. Cracking or pin holes will let the super heated air into the furnace interior and in there you have some over heating protection some look like buttons, older they look like an external thermostat, and these get the hot gas from the burners and trip then the furnace shuts down. When the furnace comes on again some times the blower will come right on because the sensor says hey this thing is hot when in fact it isn't. This also can and if bad enough will cause carbon monoxide poisoning, please inspect this closely or have a professional look at this. There is no price ever to great to replace a human life.Sorry probably not the answer you wanted but better safe than sorry!

Flame sensor needs to be cleaned. turn off the furnace power switch or breaker. pull the flame sensor located in the burner runner section of the furnace. It will be easy to locate because it has 1 wire running to it. pull the screw being very careful not to harm anything else. get the sensor out. inspect it for cleanliness. clean the sensor with light grade sand paper gently. re-install the sensor plug the wire back on. restart your furnace and this should fix 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).

Ruud IFC Furnace Blower comes on and stays running, never lites


Check on the circuit board for an automotive type fuse that is probably blown. These fuses blow because of a short in the control wiring. If the fuse is blown a lot of furnaces run the fan all the time as a diagnostic. You will have to find the short or it will just blow again.

Weather King blows fuse in Criterion II furnace


You probably have a shorted wire between the heater and the a/c. There are two wires that conncet the control power to the outdoor a/c from the heater they should be on terminal c & y in the heater. disconect those two wires and try it again if the fuse doesnt blow you have a short in the wire between the a/c & heater
