Thanks for your question,
Changing the brushes might help, but more often since you said its really stiff, something in the motor over heated and it would probably benefit you more to change out the motor, the windings could be burned up, at least you will have the peace of mind that you know your motor wont lock up again. if it were me, I would replace over repair, hope this helps, please rate this and let us know what happens, thanks again,

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.

Steven, I thoroughly enjoyed your thorough explanation of what and how it e. Really, the best I have ever read, so far.

What may have happened it that the fan sensor may need readjusting or resetting. In case you have misplaced your Owners Manual, I have included a link to it that you can download and print for future reference. Pay particular attention to Pages 6 & 7, as well as the Troubleshoot Guide. If all else fails, get a bigger hammer! Just kidding. If you find you need any replacement parts, you can order them directly for www.masterdistributors.com

Hope this helps you solve the problem.

Header just buzzes when you try to start and the blower will not turn ( reddy heater pro155 155,000bdu).


Remove the top half of the tube so that you can see the blower. Try to turn it by hand to see if it is tight. If it is tight, you may be able to oil it a little and get it to spin easier. Another thing to check would be the compressor attached to the back of the motor. There are 3 screws that hold the filter cover on. Remove the filter cover. Next, 6 screws hold the cover on the compressor. Remove that cover also. Inspect the rotor for damage and make sure the 4 fins in the rotor move freely. With the compressor cover removed try turning the fan to see if it turns easy. Be careful not to let the fins fall out of the rotor. Now put the cover back on the compressor and turn the fan again to see if there is any difference from when the cover was removed. If it doesn't turn freely once the cover is reinstalled then the problem is in the compressor and you need to figure out where it is rubbing. If it is in the motor, you will probably need a new motor.

Will not start when I press manual button then when I press the auto button, I hear a high pitched screeching sound. Is this a burner motor problem ? What is the fix? Thank You. Laser model 55...


fribue,

I am not an expert but I had a similar situation with my 55. My 55 was only making a droning sound when I turned it on. I contacted the company and they told me it could be excess carbon build up in the exhaust fan.

I accessed the exhaust fan from the back of the heater. I took a pencil with an eraser stuck it in the exhaust port and gently begun to spin the fan using the pencil eraser. After a minute or so the exhaust fan starting moving very freely. Then it worked like a charm

I hope this helps.

Electric fan motor sometimes wont start. It tries


Your unit is a year old and sits around most of the year. Disassemble the unit to get to the fan motor. When you can see the bushings on both ends of the motor shaft use a light oil such as 3-in-one to lubricate the bushings. Rotate the fan blades for a while. Relubricate. Continue until the motor turns freely. Clean up any oil spills. This should solve your problem if you haven't damaged the motor by trying to run it with dry bushings. The lubrication should be done at the end of each season and at the begining before the unit is put in service. Let me know if I can be of anymore help.

150,000BTU kerosene heater won't start,just buzzes.


Your starting capacitor is bad. It's usually mounted on the side of the motor. If not, it's the thing that the motor wires go to from the end of the motor. Usually, less than $10.

Loud buzzing after heating up


the buzzing is normal.  there is an element inside the quartz tube much like a filament in a light bulb.  as this heats up it starts to move.  where you have electrical energy you also have magnetism produced. metal objects vibrate when they are in or within a magnetic field. the element is tungsten wire and vibrates off this magnetic field.
