The single most cause of no motor output is failure of the DC motor control. Before you attempt to determine if it is the control, you must first rule out simple things.
1) Make sure you have power in the wall outlet by plugging in a lamp, etc. into the same outlet the treadmill is plugged into to test. Plug it in the exact same receptacle. Sometimes in an outlet one receptacle will work and the other won't.
2) Make sure any breakers are fuses that may have tripped or blown have been reset or replaced. Your local Radio Shack can help you test the fuses. Use the same type of fuse. Changing the value of the fuse can be dangerous or cause a fire.
3) Make sure the power switch is turned on and the safety key is inserted into the console if you have a safety key.
4) Look for any test lights on the power boards beneath the motor hood. Use caution when removing the motor hood because you may still have electricity in the motor area even if the treadmill is unplugged.
5) Test for a motor control failure. Typically if you have a failure, the treadmill will continue to turn on and operate normally until you try to input speed. If the treadmill operates on what we call a closed-loop system, it will give you some type of error message. If it operates on
an open-loop system, the computer will run normally but the motor will not turn.
6) If you have a multimeter, you can test to make sure you have DC output from the controller spades. First make sure you have 120 VAC going in to the controller. On most controls, you can use a linear taper potentiometer or jump the W and H circuits of the control with an insulated wire or insulated pliers and apply AC voltage. The DC output spades should output DC voltage if the control is good.
Next thing is to unplug the treadmill then check the motor with one these methods
Methods to test a motor:
Cordless drill battery- get a fully-charged, 18 volt (preferred) cordless drill battery and on most treadmills connect the red and black motor leads to the battery (some have different colors but if you have two wires and get it hooked up backwards, the motor will just run backwards and won’t be harmed). If good, the motor should operate at about 1 MPH.
Car battery- these are 12VDC high amp batteries so the motor will turn slowly but you can walk on the belt. Always be careful with battery acid on these things so we don’t recommend bringing them in the house…take the treadmill to the battery.
Lantern battery- a fully charged lantern battery should operate your motor at a slow speed but lacks the amperage to have someone walk on the belt.
If you have a multi meter and you don't have any of the three mentioned above, then disconnect the motor leads and connect them to the meter.Lay the meter down to where you can observe it.
Push the running belt what happens is that the motor is now a generator and by manually pushing the belt you should get a DC voltage reading( the fast you push the higher the reading) then the motor is good if no reading the motor needs to be replaced Read More At : 775 Crosstrainer Treadmill - Free Silver Service Delivery!...
