Carrier Furnance Fan / Blower Doesn't Start (Model 58GP-125-GA)

I have a Carrier Furnance (Model 58GP-125-GA) the Fan / Blower doesn't always start. Open the access panel and spin the fan then I can get it going. But it will start but doesn't start by itself.

Any ideas? The fan motor is brand new and spins freely.

Any help would be appreciated.

With power off, locate fan motor capacitor (generally silver in colour).
Rating on capacitor will be in microfarads at specified voltage ( 5mf @
370 volts). Be careful to discharge before handling and return defective
cap. to source of replacement. They can confirm whether or not truely
defective. Replace and secure. Restore power and check operation.

Purpose of run capacitor is to provide starting torque that you are
presently providing by hand spinning. Hope this helps.

Sounds like a bad capacitor usually screwed to the blower housing (round or oval shiny can)
this gives the motor a kick start)
depending on the motor there is usally two brown wires that go to it
check the mfd rating on it probably 5mfd and replace it with a matching one
its a very inexpensive part

My blower motor wont turn off in my furnance?

check the fan setting on your thermostat. On means always on, auto/int means only comes on during heating/cooling. if the thermostat is set to auto / int and the fan keeps running? you may have a bad fan relay switch. It may be integral on the primary control board of your unit.

How to make sure you Heat is working

A common problem with a furnance is the furnance will attempt to ignite, several times, you will notice that the house is not heating properly. You will hear the furnance come on and you will assume the heat is on, and the house will continue to be cool. You wiil check the furnance and you will hear it start up and the blower will come on, however a few seconds later after you have walked away the blower will shut down and there is no heat on at this time. You will again go check the furnance and after the furnance start and go through the cycle the furnance will shut down you will notice that the furnance has indeed shut down. This is the common problem of the flame sensor, you will have to remove the flame sensor, get a small piece of fine grade sand paper, and remove all the black colored carbon from the flame sensor until is is shinning bright, replace the flame sensor and attempt to start the furnance. You will notice that apatment or house have reach the set temperture, that the furnance has went through its cycle and the furnance will ignite and stay on continueously until the house obtain the preset temperture..

Furnace tries to start. Blower fan moves momentarily but doesn't.

May have a start capacitor on fan to get it started. If fan only jerks, it is probably bad. Replace if needed. Be sure to short it out with a rubber handled screwdriver or something to make it spark before removing.

I have a Suzuki Marauder 125 that just keeps cutting out????

Change the oil!

Had something very similar on my bike and the oil had gone bad as such and screwing up the running... Changed it and the engine ran so much better!!

Also check your earths... If they are bad you'll get the same...

If it works great, if it doesn't well you've changed the oil and thats always good...

Furnace is a Rudd UGEB model. Burners ignite and but the blower (squirrel cage) doesn't start. After a couple minutes they turn off and the blower starts and runs for less than a minute and shuts off....

Sounds like the fan limit was not replaced correctly. You can try switching the blower to the On position (instead of Auto), if the furnace runs properly with the blower on that would be the most likely culprit.

Furnance does not come on (first time to turn it on this season). It has power and blower/motor area heats up(I can smell the dust burning) but nothing blows out though the fan works.

You have a fan switch for the blower that's probably bad.
It only allows the blower to start and stop at a certain set temperature.
