I have a Maytag Neptune dryer,the timer countdown doesnt seem to be accurate.Does it dry over minutes, or sense that clothes are not quite dry? Seems to go longer than the time remaining time.

Type Maytag dryer timer problem into YouTube and see if the video comes up, thanks!

Clogged Vent
If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.
Normally, this is what happens during an automatic cycle:
The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.
When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)
The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.
This cycle continues until the clothes are dry.
But...if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.
Heating Element
Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace the heating element. You can check for an ohm reading but will need to refer to the service manual for proper reading. This sometimes on the tech sheet located somewhere on the dryer. Usually between 9-13 ohms.
Cycling thermostat
Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork . This thermostat usually has four wires going to it. Check the 2 terminals that are opposite each other and are the closer together of the 2. These 2 terminals should have continuity. If not replace the thermostat.

most dryers have two heating elemts and when one goes out this increases the drying time and could cause a elec. short and trip a braker can be replaced.. There is also a saftey switch that goes bad and will not let the heating elemt work properly ?

there isn't a timer on this machine,you have a control board,if the time isn't counting down correctly sounds like you have a bad control board that's inside the console

your timer is the problem if its not moving
which can be expensive
60-80.00 dollars Dryers are cheap enough to buy a good used one

I suspect you have a blocked air vent. A blocked vent will definitely extend your drying time. You may even find yourself having to run a load twice to get it fully dried. One way to confirm this is to disconnect the vent hose from the back of your dryer and dry one load with the machine venting directly into your laundry room. If that load dries quickly then you know the problem is a blocked vent. Most vents get blocked by lint near their exit to the outside. There's usually a screen at this location to prevent small animals from crawling into your house. Often this screen gets clogged with lint. Most vents are designed to allow removal and cleaning of this screen from the outside.

Has air flow problem, check to make sure the vent going to the outside is not blocked. If it isnt, you should be able to take off back cover of dryer. Should be a duct that air goes through, take it apart and make sure there is no lint in bottom of it. I had the same problem and that fixed it.

It sounds like you may need a new timer. Has water or anything gotten into the timer. This could be causing a short or faulty reading in it.

the glow plug sensor not accurate send to timer /replace sensor
