Re: whirlpool model # lgr7646ez3
Here are a list of causes that may contribute to this lack of sufficient drying.
CAUSE • Lint screen is clogged with lint. • Restricted air movement. Exhaust vent or outside exhaust hood is clogged with lint. • Exhaust vent is crushed or kinked. • One fuse is blown or circuit breaker is tripped. The dryer will appear to operate, but you will not get any heat. • Cycle Control knob or temperature selector is set on air dry. • Load not contacting the sensor strips and automatic cycle ending early. • Fabric softener sheets blocking exhaust grill. • Dryer located in room with temperature below 45ºF (7ºC). • Large amount of moisture in the load. • Cold rinse water used. • Load too large and bulky to dry quickly.
Here are the solutions to combat the issues.
SOLUTION • Clean lint screen. • Run dryer for 5-10 minutes. Hold hand under outside exhaust hood to check air movement. If you do not feel air moving, clean exhaust system of lint or replace exhaust vent with heavy metal or flexible metal vent. • Replace with heavy metal or flexible metal vent
• Replace fuse or reset breaker. • Select the right cycle and temperature for the types of garments being dried. • Level dryer. • Use only one softener sheet per load and only use it once. • Move dryer to a location with temperatures above 45ºF (7ºC). • Expect longer dry times with items that hold more moisture (cottons). • Expect longer dry times. • Separate load to tumble freely.
This will help you fix this problem. i suspect an exhaust obstruction.

Have you opened the door while its running to see if its warm inside (heater working) If its getting warm and still not drying the clothes properly you likley have a air circulation concern. With the unit running check the exhaust vent outside from dryer it should have a good flow of warm air, if not you have a restriction sowher between the unit and outside. Heat alone will take forever to dry clothing,you need good air circulation to remove the moisture from the clothes otherwise all you will end up with is warm moist clothing.This generaly happens over a long period of time and then all of a sudden you realize the dryer is not working like it use to..Hope this helps you with your concern.....
If it is in timed dry mode, the problem is in the timer, if it is on sensor dry then you may have a clogged line. Easy to check, disconnect vent from back of machine and run it, if it dries without a problem then you need to replace or thoroughly clean venting. If it still does the same thing, check your thermostats, like the cycling thermostat, that is what advances the timer in sensor dry mode. What do you mean by tripping off? Do you replace the high limit fuse to get it to work again or does it just shut down?
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.
Try running the dryer with the vent pipe unplugged. There should be a lot of hot air coming out, if not the insides need to be cleaned. If it really moves air, and dries a load ok unhooked, your vent is clogged. Clean it if you can. If you can't, look into a lint trap that will work for your situation, some have a water trap, some are good filters, etc. If the air is not hot, some of the electric element may be bad. If it's gas, it could need a tune up and cleaning inside.
the wire my be off the sensor , but when you say it worked after cleaning vent makes me think the vent needs more cleaning, the dryer is designed to run until the clothes are dry if that takes 4 days it will run 4 days, if the vent is not good it cant dry, remove the vent and run a load see what happens with out any vent on it
