LER8648LW0 Dryer. Not heating, runs continuously (stops w/ door opened). Timer not advancing. Checked fuse(0 ohms), thermostats (0 ohms) and coil (10 ohms). Timer was at 10-11 K ohms,(high end). So wondering if timer affects ability to get power to heating element? Power goes from timer to motor relay (centrifuge) and that handles start, stop, heating, and cycling? Any input appreciated, I have the timer on order $100 + tax already.

Hi Jesse
Here are a few things to check:
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or the dryer,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor/thermal fuse one at a time by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor/thermal fuse as it is faulty.
If you have an ohm meter then you can test the thermostat/thermistor/thermal fuse,
then you do not have to tape the wires together as described above.
To test your thermostat/thermistor/thermal fuse remove the wires from the thermostat/thermistor/thermal fuse and check for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST AS THIS COULD CAUSE A FIRE BECAUSE YOU HAVE REMOVED THE SAFETY.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc.
If the thermal fuse overheats the dryer will not operate. It's located on the blower housing. It cannot be reset.
You can test it with an Ohm meter or continuity checker, remove both wires from the thermal fuse and put the test probes to each of the ends of the thermal fuse, if no continuity then replace the thermal fuse.
A vent clogged with lint can cause it to overheat.
Right after replacing a dryer element, always run the dryer on 'air fluff' / 'no heat', and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

Notes: Check all components on dryer with at least one wire removed and all have continuity or 0 ohms.
Have checked circuit breaker and know for sure 240 volts is going in machine (motor runs on 120v heater needs 240v).
Ok the next thing to do is find the heavy red wire going into the timer. Remove the red wire from the timer. Set the timer on heat dry cycle (power if off) Chck from that leg of the timer to any other leg on the timer for continuity. or 0 ohms. if you get nada then the contacts inside the timer is bad.

test the push button for open and faulty .However see this causes too.

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.

Same problem with my Whirlpool Dryer: Model LER4634EZ2 which stopped heating. I checked the coils that was "OK" then I checked the fuse that was "OK" I replaced the Thermal Fuse and High Limit Thermostat then after starting the dryer the heat came on ... problem solved NO.... the dryer just kept running and running until I opened the dryer door. Not going to put 70 or so $$$ into this 10 year old dryer which up until 12/15/2011 worked fine.

Sounds like you have two problems
1...Timer...Replace the timer as it is non repairable.
2...Heating problems...check below

If all of the components are reading ok then you need a timer. Touch your 2 leads together. 0 ohms rght. That means you have a complete circuit.If you get the 0 reading then the element must be otay. Bad timer. Take that fancy meater of yours and atttach one of them leads to the timer leg marked RH. Yank the wire off the terminal beore you test. Move the timer around. You should get the famous 0 reading along the way. If you don't then that means you have the bad timer.

If you need further help, reach me via phone at https://www.6ya.com/expert/dan_73bbd84fe1d95b61

Test for these first:
First of all, see if you have good voltage supply on the socket on which it is powered too.

(1) All venting is clear of lint, even disconnected from back of dryer.

(2) Breaker in house is not tripped. Cycle the breakers off and back on to make sure.

(3) Test continuity on all thermostats and thermal fuses, all have to measure 0 ohms when wires are disonnected and dryer unplugged. We tested the HiLimit Thermostat, Safety Thermostat, and Thermal fuse mounted to the heating element housing, all should have continuity. Also measure the two thermostats located near the exhaust duct in the rear of the dryer, get 0 ohms as well.

(4) Disconnect wires from heating elements. Test continuity from each terminal to the metal cage to make sure none of the elements were grounded. Good if theres no continuity there.

(5) Disconnect wires from heating elements. Test resistance between double coil and inner/outer coil. Each should measure around 19 ohms.

(6) Test the dryer temperature switch by removing wire from terminal 15, then took a reading between terminal 15 and terminal 16, should get 0 ohms there.

(7)Test the dryer timer by first setting the timer to 60 minutes. then remove the wire from terminal A. We then took a reading between terminal A and terminal B, and should get 0 ohms. then keet the leads on those two terminals and rotate the timer and had continuity throughout the 70 minute cycle.
