I think I had this same problem last year. Forgot to change out the filter on a regular basis and just above the filter box below the heat exchanger there is a air flow sensor. In my case, I had to replace it. It should be continuous for it to work properly. One way to check to see if it is the problem is to bypass it temporarily by shorting across the sensor leads and seeing if it starts.

What is a DIVERSITECH BLOWER MOTOR WG840587 wiring


Have a look to following link:

and:

This must be a 115V AC single phase motor.
That means you have to connect it to your normal power supply system, 3 wires, 1. phase, 2. zero, 3. protected earth. That's all.

92 buick century blower motor replace? I have a 92 century that im trying to replace the blower motor on. the problem im having is that i cannot get it to slide out because it hits the power steering pump....


Found this info. I don't know liter size of engine? For the 2.2L rotate the engine forward slightly. Some, I have removed the squirrel cage from the blower, then removed. I don't know if that would be applicable on your vehicle? As far as the power steering pump, I'd have to look at mounting bracket. All I can do is throw out ideas, I can't see anything from here.

Blower keeps running even after thermostat is in off or in auto? The forced air unit stays on even after temp setting is reached or will switch thermostat switch to off. The heat stops but blower stays...


This could be an indication that there is an error code flashing on the control board and needs to be addressed. Most newer units like this indicate a problem by running the room air blower to alert the homeowner something is wrong. Really! Without shutting off the power to the unit, look for a small viewing port that looks into the cabinet. You should see a blinking light that will blink a number of times, pause then blink another number of times. Once you get this number, say 3-4, look at the wiring diagram pasted on one of the door panels for a diagnostic chart. It will give you a starting point where to look for the problem. If you have one. Or you could have a bad control board or shorted wire. Make sure the air filter is clean since you will be in front of the unit, you would not believe how many times I have to charge $100 to replace a filter the home owner could have done for less than $20.

Unit will not operate when turned on and a red light pulsates next to the


That blinking light is an error code. It will blink two different numbers such as three blinks, pause, then four blinks. Once you get the combination of blinks, look at the wiring diagram pasted on one of the panels for a diagnostic chart. It may help you pin point the problem area.

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).

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.

1997 buick century - blower stays on when car is off


The blower motor relay is stuck, holding the curcit engauged. Look under the hood, find the conveinence center, where you will find fuses and relays (read the cover, see if one says AC/Heater blower relay), if not, look in your car's manual, to see where this relay is located. When you find it, pull it out, see if the moter stops, if ti does , replace it.

Blower comes on but no heat


If there is a problem with the furnace, it will display a number of blinks on the circuit board. You will need to look thru a small window because if you take off the access door, it removes power from the furnace and erases the code. Once you count the number of blinks, now remove the access door and on the reverse side you should find a diagnostic error code chart to get you started looking in the right direction. If there are no blinks, it means that the thermostat is not sending a signal to the furnace to start (check the thermostat for proper operation and wiring).

I hope this helps.
