Question about Desa International R70DT Oil Filled Utility Heater

1 Answer

My Model R70DT will not light and run

When I plug unit up all I get is a Humming sound like the motor is frozen. I have removed the top and the motor does not turn free as it should which idicates to me it is a motor problem. I have in the past take motors of this tyoe apart and free them up using a good grade of oil to clean and lubicate them. In this case I do not have manual and I'm not sure what and how all the parts attached to back of motor work.
If I need to replace the motor where do I get one?
Could you please attach a manual for future use?
Thanks in advance for you help,

Here is a link to the manual you requested... http://12.153.20.74/manuals/111167-01C.pdf. It could be that the pump rotor is binding. Check to see if there is debis in pump, if so blow it out with compressed air. Check the gap pn the rotor.(Adjust to .076/.101 mm) On page 14 of the owner's manual you can find pics and instruction on checking and servicing a pump rotor binding. If this does not work for you, then I suggest you contact Master Parts for the parts you will need. You can contact them toll free at 800-466-1446 or online at www.masterparts.net.

Hi, Like any washer if you smell something burning and a humming from the motor I suggest you take out any cloths in it and try turning the inside basket clockwise to see if it turns freely and if it does then the motor is defiantly shot but if it won't turn freely then either something is jammed between the inner and outer tub or the transmission if it has one is bad or the bearing housing is bad so try and disconnect the belt from the motor and see if the motor runs and if it does then follow from the motor to the tub and see what is frozen .

Good Luck

I have an older amana central ac/heating unit, fan not turning outside, did pencil test, turns slowly then stops. changed capacitor a month or so ago all was fine. started making a humming noise so ran and...


Sounds like the fan motor has reached its endpoint. It will have to be removed and replaced. Find the dircuit breaker in your electric panel that supplies power to the air conditioner unit. When you have found the right one, even the humming sounds will be absent. The fan usually is at the top of the unit. You must have opened this to change the capacitor. Remove the fan band motor as a unit and take it to a store like Grangers and determine if they have a motor that would replace the one from your unit. If the motor has a model number on it, you may find a replacement available onlilne by Googling that number and the name Amana. Put electricians tape over the wires that led to the motor, just in case someone turns on the circuit breaker before you have completed the job

Check for a failed capacitor under the control panel It is a start/run capacitor that the motor needs to start running. The motor will hum and if left will eventually burn out.

I have a Kenmore top loading large capacity washer model 1028882791. It began washing as usual then began to making a loud humming sound. The agitation stopped. It only makes a loud humming sound. I...


The humming sound is coming from the drive motor running but unable to drive the agitator nor the basket to spin. The drive motor is definitely running as the drain function works because of the fact that drain pump is directly coupled with the rear spline of the motor. The drain pump works in either direction as long as the motor runs. The problem is obviously a broken motor coupler which transfers the mechanical energy of the motor to the transmission. The solution then is to replace the broken coupler. Click on the link below for the detailed step-by-step procedure in replacing the motor coupler.

Motor humms but door doesn't go up or down!


5 flashes is the code for "RPM sensor board or motor overload." If your door is stuck in the open position the trolley may be jammed against a bolt just in front of the motor unit. Remove the bolt and run the opener until the door is closed. Now locate the 'up limit' control on the side of the motor unit and turn it a couple turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt.

Kenmore washer 20712 series 70 will fill but nothing else


Check at the back side of the motor to see if it turns freely. If it does, your motor is bad. If not your gearcase is frozen (bad). Hope this helps!

Motor malfunctions usually call for service by a professional. There are three main causes of motor failure: lack of lubrication, a defective motor switch, or worn or frozen bearings. A humming sound can be related to a burned-out motor or a defective switch. Check these trouble spots before you call a professional service person or take the motor to a repair shop. Here's how to check a dryer motor:
Step 1: Remove the back access panel. Then reach behind the drum, motor pulley, and idler arm pulley. If these areas are clogged with dirt and lint, undue strain on the motor may be causing the humming noise. Worn or broken belts can also cause a humming noise. Check the belts for wear and damage. If the belts look all right, you may be able to stop the noise by spraying them with fan belt dressing, available at automotive and hardware stores and home centers.
Step 2: Turn the dryer on. The noise you hear may be the whirl of the spinning drum, not the motor. Some noise is normal.
Step 3: Force a little 20-weight nondetergent motor oil (not all-purpose oil) around the ends of the motor shaft. This lubrication may stop the humming noise. If this doesn't solve the problem, remove the motor and take it to a professional service person.The centrifugal switch on the dryer motor may be located on top of the motor. Humming, no motor power, and no heat can be caused by a faulty centrifugal switch. If the switch is externally mounted, check the terminals of the switch to make sure they are tight and not burned. If you spot trouble, remove the switch and take it to a professional service person for testing. A faulty switch will probably have to be replaced. Some centrifugal switches are located inside the motor housing; you won't be able to remove the switch in this case. Remove the entire motor and take it to a professional for repairs.
If the motor hums, but won't run the pulley on the end of the motor shaft, try turning the pulley by hand.Caution: Before turning the pulley, make sure the power to the dryer is turned off.
