I have installed two Maytag dryers and neither will work, although an old Kenmore dryer does work at the same location. The Maytags hum and then shut off. Same thing happens again after I allow time for it to reset. One of the Myatags is a new model and the other is relatively new. Any suggestions? Thanks.

It would be very difficult to offer any sound diagnosis based upon the sketchy information in this post, however, after thinking this over for a short period I am left with a couple questions that might lead to a clue here.
1. Are these gas or electric dryers?
2. Given that you have tried 3 relatively new dryers at the same location I am left wondering, is this a residential application or perhaps a small public access laundry (laundramat or multi-family dwelling laundry room.)?
3. What is the specific Voltage, Amperage and Phase on the Data Plate for each respective dryer?
Fundamentally all dryers work the same, so there should be no problem in using one brand in the place of another, but if this is as I suspect a small multi-family or public access laundromat, or if the machines were originally obtained from a laundramat, there is another parameter that comes into play.
I am going to go out on a limb here at take a stab at what the problem may be, but in order to offer any real help we would need to know the type of fuel, gas or electric, Voltage, amperage and phase listed on the machines, and the voltage (Measured at the location), Amperage rating of the supply breaker, and phase of the electrical service, either single or 3-phase.
Normally if a motor hums but does not start it is indicating there is a problem with the start relay, start capacitor, or the start winding on the motor, however, if the Kenmore works okay, and two Maytags do not I am left wondering, why would two Machines exhibit start winding problems at tha same time? The odds of that are very slim.
The only possible solution that comes to mind is that these may be commercial machines, and in that case the kenmore may have a single phase motor while the maytags may have 3 phase motors.
A single phase motor has two sets of motor windings, the run winding and the start winding, and it requires some form of a start relay or capacitance circuit to control the fundtion of the start winding to establish rotation on startup.
By contrast, a three phase motor has 3 separate windings and the rotation is determined by the sequence order that the windings are energized.
If the two maytags happen to have 3 phase motors, and are being plugged into a single phase circuit, only two windings at best are being energized, therefore it cannot establish either rotation or full run potential, while the kenmore may be a single phase machine and works fine at this location.
