System won't budge

When the power switch is turned on, the fan motors will move one quarter turn. No screen, nothing.

Sounds like a power on/power good signal fault. Could be the power supply or the mobo. The voltages can be read at the ATX connector: http://www.formfactors.org/developer\specs\ATX12V_1_3dg.pdf or you can try another if you have a spare power supply to verify whether it is a mobo problem or power supply. Also there are power supply testers but they cost almost as much as an inexpensive power supply. It's an easy replacement task. Steve Medley

I have a 98 bonneville se. the blower fan only comes on when the knob is all the way up and it ONLY blows heat and absolutely no cold also the air only blows out the defroster and the floor


How did you test the A/C system ? Hook up gauge manifold , test A/C pressures ? Manual or automatic climate control ? The blower motor only working on high means the blower motor resistor is bad ! Did you hook up a scan tool an check high an low pressure switchs inputs to the PCM - engine computer . Does the A/C compressor clutch engage ? turning on the compressor ? Moving the mode switch does nothing . Doesn't move from floor to vent to defrost ? Probably the mode door actuator ! Don't think the HVAC control panel is bad . Just a few little things . Pushing the A/C button on the control panel just send a electrical signal to the PCM , the PCM will energize the A/C clutch relay , turning on the compressor .

Beater bar motor quit, now the main motor quit. Replaced the on/off switch. still nothing


see this causes and fix it. God bless you
If the vacuum cleaner motor doesn't run the on - off switch might be turned off or defective. Test the switch with an Ohm meter or continuity checker.
If the vacuum cleaner motor does not run the motor itself might be burned out. Check the power switch first to be sure the motor can get power. Then, be sure the motor shaft can turn freely, that nothing is obstructing it. If the motor can turn freely and is getting power but still won't run it will need to be replaced.

Badger disposal has power, inside small blades move but allen wrench only does quarter turn on bottom. I tried a broomstick and it still won't budge. Don't think it is rust since it is only 5 years...


When you turn it with the allen wrench, does it move a quarter turn fairly freely, then stop abruptly? If so there is something stuck in there. (Like a hard piece of bone, or glass but probably metal) Have a helper work the allen wrench while you look down in there with a nice bright light. On the other hand, if it moves a quarter turn but is very hard to turn for that quarter turn, then I am afraid you have some kind of fiber (string, fabric, or tendon) wrapped around the shaft where it would be very hard to get to. If that is the case, you might try removing and plugging the drain hose (that goes to the sink trap) and using some drain cleaner and letting it soak for a while --- but that is tricky because you will have to drain it out the hose wearing rubber gloves and full face protection. Good luck, Al K

Hello, I replaced a light fixture on my existing Emerson ceiling fan. The light worked right away but the blades didn't turn. I could hear power going to the motor so I went back into the switch cup and...


Signs of a bad capacitor in a ceiling fan include:

  • Fan runs slowly or not at all on all speeds
  • Fan will not start but will spin if started by hand
  • Certain speeds are slow or do not work
  • The motor hums and turns freely by hand but will not spin

    The capacitor is usually a black box inside the switch housing of the fan. If this box appears burnt or melted in any way, that is also the sign of a bad capacitor and it should be replaced.

    have a good day !!

    Heater is dead


    My 2000 century heater blower died,dont replace the fan motor until you check with a simple test light to see if the heater fan resistor is bad first,it's only 20 bucks to replace.Its located next to the fan housing up against the firewall.The wires from the fan switch go down to the resistor, check to see if switch has power then check for power down at the resistor,I'll bet its the resistor.There are three, I think five sixteenth screws to remove the resistor one is crammed up very tight on the firewall,you'll need a quarter inch drive extension with a wobbly socket to get that one against the firewall.

    P4M-915G/PD1 no screen, no BIOS, only power.


    Do you hear any beeps at all? Do you have a system speaker on the motherboard? If not, plug a 2-pin system speakers onto the motherboard where it says "speaker" and listen for some beeps. You may have a fried CPU or dodgy RAM on your hands. Possibly even a faulty AGP/PCI-E slot, to name a few.
