Motor Running backwards.

I can get it to run properly by turning the motor the proper direction when starting but as soon as it stops then starts on its own it runs backward and shuts off immediatly.

Why would a torpedo heater fan turn backwards? every time I start my all pro 115,000 heater the fan starts to spin counterclockwise and the heater wont ignite. But when manually spin the fan blade clo

If the fan has a 'run' capacitor, in rare cases, a faulty capacitor will cause a single phase motor to start in reverse. In most cases a faulty capacitor will cause the motor to only hummmm and not start or start slowly running the right direction then overheat and shut off.

See if there is a capacitor, change it first. If that doesn't fix it it sounds like its time for a new motor.

Look for a capacitor. Have it tested, it may be a start capacitor for the motor, which would get it going the right way. Don't worry about polarity on the cap, but you can mark the connections if it looks important.

Heater unit will not ignite, will note fire up

Check your furnace by the electrical panel, there should be a blinking error light. Sometimes there is a legend to how many blinking lights means what. I had an issue with mine, read the code and it turns out it was hitting the high heat limit. Turns out my blower motor wasn't turning on. Replaced it with a spare and it was fixed. Find out what type of furnace, and google the name, model, and the words, 3 blinking lights. Does your furnace turn on at all? Does it start to go through the cycle then stop? This is the proper cycle of a furnace and what should happen.

Inducer motor kicks on, it runs for a little bit, about 3-5 seconds, then you should see a bright yellow glow, this is the igniter, shortly after, you should hear a click and the gas should start to flow, almost immediately it turns to a blue flame. Then your igniter should turn off and the blower motor start up.

Dayton 100K btu kerosene salamander heater - been running fine until last night. Unit is about 15 yrs. old. Ran for about an hour , then tripped out. I reset it and it would run for 1 - 2 min. and trip...

On that motor there should be a thermal overload to shut motor off in the event that it gets to hot. There also should be a start capacitor and if it is getting weak that could account for the unit tripping the breaker if it is trying to draw to many amps on start up. I would start by replacing the capacitor with plan to install new motor soon.
You may be able to extend the life of your motor some by giving it and fan a good cleaning, Good luck and thank you.

On l-56 stove an error code EE 8. what is this and can it be repaired?

The blower motor is not working properly. Turn the stove off and remove the front cover. Remove the lower baffle in the front. Remove the black hose that is about 1 1/2" in dia. If it breaks don't be surprised. Stick a pencil in the hole and spin the fan. Keep trying until it spins freely. If it spins freely from the start the motor is burned. Put the black hose back on and try to start. IF the hose broke you will need a new one. For now put some electrical tape around the break to get you going.

Keep us posted.

My outside unit is working but it doesnt seem that the inside unit is blowing or working. It just hums and shuts off. Model is Gmp100-5. Is the fan/blower motor gone? Where can I find the part?

Hi, if the motor hums that tells you there is power to it already. Take a look at the run capacitor mounted on the side of the blower housing. Look it over for signs of oil leakage, swollen out of shape. Its more then likely a 5 microfarad UFx 370volt run capacitor depending on the size of the H.P. of the motor. Like the other fellow said, you can spin the wheel/cage to make sure the bearings are not froze up. Most blower motors are air-over motors and are oil type bearings. You can remove the run cap and take it to any appliance parts house to have it checked out with a ohm meter before you buy one. That will rule that out. More then likely, you have lost a winding in the motor it self and will need to have it replaced. Its either a 2 or 3 speed motor, medium for heat and high for your a/c. Low is extra. For about a $1.15 you can get a zoom spout oiler at the hardware store and remove the caps/plugs to put a few drops of oil on the bearings. This motor will get very dirty and dusty as it is where the return air comes back through your a/c filter. They do get hot and burn out due to this. Before I would go out and buy a motor if you are lucky enough to find one at a appliance parts house, I would oil the bearings if they are not sealed, look at the back end for a plug or cap first, and have the run capacitor checked for proper UF as it has to be with in 10% of its rated value. If this doesn't take care of it, I would recommend having a tech come out to install this motor. It is one of the most difficult to change if you have never installed one. Call around and get a estimate. I would charge you a flat rate of $175.00 complete with new run capacitor, not by the hour. It takes around 1 & 1/2 hours to do and have them clean the blower vanes while it is out also. The shaft size on the motor is 1/2"x6" long, maybe a 1/3 to 3/4 H.P., 1075 R.P.M.'s. I hope I have been of help and given you some direction. Please keep this in mind when rating me as I know you will be kind. Please keep me posted on the outcome by my user name below.

My Reddy Pro 150 does nothing when plugged in. I

in the unit there is a motor and beside motor there is a capacitor.its called starting capacitor.if this capacitor is blown the motor will not start and if motor will not start machine will not start even though you have proper power in the machine.Your starting capacitor is bad. It's usually mounted on the side of the motor. If by chance the capacitor is ok.and shows proper reading value in meter test,then it's the thing that the motor wires between the motor and the capacitor . Usually, less than $10. the capacitor is available at any local electronic hardware shop. ------------ This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

Goodman GMP075-3 Random Incomplete startup

If the draft motor starts then shuts right off and then a red light comes on usually means that there is a blockage somewhere. Check the pressure switch line, make sure that it is clear and the hole in the heater that the pressure switch vaccum line runs to is open. If that checks out then make sure that your flue vent cap is on and that it is not pressed down on the flue vent and that the gases can vent properly
