SOURCE: fan is constantly on, flame never comes on

You have a bad ignitor or ignition system part. The system is designed that if the is a failure in the gas heating then the fan runs and doesnt shut of so you will call someone to fix it .They all do this.

SOURCE: westinghouse 3-way fan switch can not be turn off.....

I had a similar problem. A replacement Westinghouse 3-4 wire 3-speed replacement switch from Home Depot, part # 77020, is a multi-pole that did not work with my ceiling fan. There was no "off" position. I found the correct replacement switch, sold under the "Harbor Breeze" name, part # 033905, which is a single pole switch, at Lowe's, at a better price!

If you have both heat and ac running that means that the Yellow , AC and the White heat circuits are both being energized with the Red 24 volt hot leg that enters the tstat on the R terminal, note the Auto fan switch between Yellow and Green if Normally closed that is the Auto setting and high speed fan comes on for the Cool mode via the fan relay,
while the Heat speed is low speed and controlled not by the fan relay but the temperature or time delay, you need to determine what speed you have running now, low or high? if you flip the fan switch to ON and it speeds up then it was on low, if it makes no difference you have high sped running already.

It wont start. the hi temp and heavy button are the only buttons that come on


OK I am not an expert but I have spent the last two weeks learning about and fixing my dishwasher! Hopefully I can save you a headache. Try the following:

* Flip the switch off and on in your breaker/circuit box. May reset your washer.
* If that doesn't work, try running diagnostic/reset cycles by pressing heated dry -normal- heated dry or heated dry-sanitize-heated dry in sequence. If the cycles run fine, you will rule out a power, latch, motor/drying issue. It also may (hopefully) reset your system.
* If normal function still does not resume, make sure your power (from the breaker box) is turned off and unscrew (with a star-shaped screwdriver bit - check your car emergency kit/toolbox, you may find you have it) and open the front button control panel and check all connections. Try carefully unplugging and replugging wires and look for any corrosion/moisture on the circuit board.
* If that does not work, test the circuit board by unplugging the green ribbon cable from the control panel, reassembling with the ribbon cable unplugged, flipping your circuit back on and then closing the dishwasher door. If the drain motor runs, it will show you that there is still some function with the circuit board. Although it doesn't rule out the circuit board completely, it will point to a most likely control (button) panel issue and try replacing that. If the drain test does NOT run, it may be the circuit board that needs to be replaced.

Hopefully some of that helps!

Carrier 48NMX042 IFM wont stop, condenser fan motor and compressor wont run


Ok first thing is it sounds like a wiring problem. So first step is to make sure the thermostat is properly connected. Which... the main thing here is there needs to be 24v dc power coming from your control board (transformer) going to the thermostat..generally that is the red wire. All the thermostat does is connect that "red" wire (power) to one of the other wires to complete a circuit. So make sure you have 24 volts... (generally about .5amps) . if you have power than switch thermostat to fan only should energize the green wire only. then switch to ac and move temp low enough that the ac should turn on and that should energize the yellow wire. for sure one of those wires is incorrect now or the fan wouldn't be on OR THE THERMOSTAT IS NOT CONNECTING THEM AND IT IS BAD. Now about the compressor and fan.... those same wires run out to the compressor unit... ok the yellow for ac.. greeen does not go to compressor unit that is for fan only (vent).. red carries the same 24 volts... one difference here is that most carrier units only have the one transformer....so you run the red wire is the +pos 24 volt..and then a "common " wire is needed which is the Ground or neg... that wire on a carrier is brown usually but could be different depending installer. The orange wire goes to the pump reversing valve it is always energized when on ac mode...when heater is on in the winter it is heat pump and is not energized so just connect the orange and yellow together... tell me more specifics if this doesn't help and i'm sure I can help you... thanks Chuck

Hi Maurice.

Circulating is Fan Assisted mode. In this mode the fan kicks in when temperature is reached and runs all the time.

Here an extract from manual.

There is no preheat unless you set temperature. That is why you get the fan from start.

Laptop beeps4 times but doesn't come on the monitor or start-up. ights on front of laptop and start button come on but nothing else happens.


In most cases this means bad memory stick. If you are able to, flip over the laptop, find the panel that has the memory under it, unscrew the screw(s) to get the panel off, and pull out the top stick of memory. Flip the laptop back over and power it on. If it works fine again, then that stick was the problem, and you can go buy a replacement and install it back into that slot. If that doesn't fix the issue, turn it off, flip it over, pull the other stick of memory out and put the first stick into that slot. Flip it back upright and turn on again. If that fixes the issue, then the second stick of memory is bad and you can just replace it as well. If neither of those fix the issue please reply on here and we can do further diagnostics.

Can't remember where they are exactly on yours but there are a group of three or four relays either back on one of the fenders or on the firewall. One of those is for the fan.

With my thermostat on auto and on heat, and the furnace turns on, the fan will not turn on with it. If I switch the fan to on it will run after I repeat back and forth from auto to fan on several times...


Well, here is the deal: unless you rewired from two wire to multiple (usually 4 to 10 wires) wires, the fan cannot be controlled from the thermostat, even though the thermostat indicates that it can > it is a physical wiring and fan administration issue.

Unless you have a newer furnace, the fan is controlled by plenum temp. Works like this: burner turns on, no fan until the plenum temp reaches set temp,....then burner off, and fan keeps running until pelnum temp drops, and often the fan may kick on a few more times as this temp depletes.

We do not know how to turn the whole house fan on. Does it work through the thermostat on the walll for the air- heat switch?


To turn on your whole house fan, got to you thermostat. Open the door and look for where it says fan, most will have a selector switch to select "auto" or "on". You want it "auto for it to work properly with your furnace and or central air. If you flip it to "on" it will run 24 hours a day none stop, warning this may shorten the life of your fan a little.
