Todd January 21, 2021 for Model Number 11097586200 Kenmore Gas dryer is heating up for 23 sec and shutting off heat for 2 min 23 sec and repeats for the length of time set. This is for all heat temp selected MED, MED/HIGH, or HIGH. I have replaced the coils and the Cycling thermostat and the problem continues. What am I missing?
1 Answer Todd, Remove the vent from behind the dryer and see if the flame stays lit. You could have a venting issue causing the unit to short cycle. Read More...
David January 04, 2021 for Model Number 66801690. 66801 Dryer not heating. I’ve tested all thermal switches and they tested good. Incoming voltage good. However the temperature selector switch/knob has no continuity. Is this likely the cause of no heat? Part # is 3399640
1 Answer David, Based on the information provided the heat circuit goes through the selector switch, so if it is open then it would not apply power to the heater. Read More...
Nicholas January 03, 2019 for Model Number WED5560SQ0 Thanks for tip. I pulled the dryer away from the wall and took the back panel off, even the exhaust hose. I ran a white load of towels and clothes and they all were a little damp. What thermometer would I need to check for temperature of the air and would I still have to change the cycling/operating thermostat off even though it still has continuity?
1 Answer Hello Nicholas, Showing continuity does not tell you at what temperature the thermostat opens. If it has been thermally stressed, it may be opening at too low a temperature and not closing soon enough, creating a cool dry condition. The dryer exhaust that runs through the home should be checked for a full 4-inch diameter opening all the way to outside atmosphere. Read More...
Nicholas December 30, 2018 for Model Number WED5560SQ0 I think something is up with my dryer Whirlpool model #wed5560sq0. It's not heating. I checked all the components and wires and they all have continuity. There's good airflow going throughout the machine and I even pulled the dryer away from the wall with the hose still on and it's flowing fine and out the apartment. Plus the lint trap was clean before starting the load. The last thing I did was thought it was the temperature selector switch. The high setting was not getting continuity on the high setting for 10K ohms, so I rigged a resistor of 10K ohms and attached it to the selector switch terminals on the timer to make the dryer think it's the selector switch after I've took the real one off and set it to the side. The clothes are still damp after I've run it for 60 - 70 minutes. Is something wrong with the components, even though all, including the heating element is fitting their continuity and have continuity? Or is there something else wrong that won't let my dryer dry completely for a full 60 minutes?
1 Answer Nicholas, i would pull the dryer out and away from the wall, remove the dryer vent and run a load of clothes or towels to see if it makes any difference as to the length of time it takes to dry the load, this way you can eliminate or confirm the vent system. If it still takes a long time, with a empty drum, check air temperature at the exhaust behind the dryer, you need to see about 160 degrees, if the temps are not hot enough, replace the cycling thermostat located by the blower housing, part number is WP3387134 Read More...
Nicholas December 23, 2018 I read your last message. Thanks for the lint trap for my Whirlpool model #WED5560SQ0. The bias heater? Is that on the operating thermostat? Because of what you said about the heater getting bypassed on the thermostat it sounds as if that's what gives the dryer selector switch, model # WP3399640, it's high setting resistance. Is that true? Because we thought there was another resistor inside the selector switch to give the high setting. All our wires on the thermostat and thermostat heater, bias heater, are working fine and got continuity, by the way, including the wires on the selector's wire harness to the timer.
1 Answer Nicolas, the cycling thermostat has a built in heater that adds a small amount of heat to the thermostat when it is in a delicate or low heat setting. This makes the thermostat open up a little quicker to turn the heater off, thus allowing the heat to stay at a lower temperature. It is also referred to as a bias heater. Read More...
Nicholas December 20, 2018 for Model Number WPW10717210 Question about the lint trap for my whirlpool model #WED5560SQ0. It fills up halfway after a regular 60 minute dry cycle, then I have to dry the clothes for like another 50 minutes to dry the load completely and the lint trap fills up completely. Is a full lint trap mean dry load complete? And does a half full lint trap have got something to do with the dryer selector switch not having continuity on high setting? And finally what's the resistance on the high setting under 10K ohms?
1 Answer Nicholas, Lint accumulates on the filter as the articles dry, it also depends on the type of articles, cotton(towels, t shirts, etc. produce more lint than polyesters or man made materials. If it takes 2 hours to dry a load, you need to check the exhaust vent pipe and vent hood, it should take 45 to 60 minutes to properly dry a standard size, mixed load. The temp. selector switch has little or nothing to do with the lint filter, it controls the temperature in the drum. You should read 10 ohms resistance across the terminals when the switch is set at the lowest setting, and 10k ohms across the terminals on the highest setting(+/- 10%) On the low/med. heat setting power is applied to the bias heater inside the operating thermostat, this causes the thermostat contacts to open"early" and reduces the temperature. On the highest setting, the bias heater is bypassed and the thermostat opens and closes at the preset temperature( approx. 150-160 dgrs.F.) At this point, it sounds like you have a clogged or kinked exhaust vent or vent hood or the overall length of the system is too long. Make sure you're not overloading the dryer. Read More...
Nicholas December 19, 2018 for Model Number wiring diagram Got a few questions on the wiring diagram for my Whirlpool model #WED5560SQ0. The wires 1 - 6M wires, are they for the motor? The TM initial, does that mean Timer? And last but not least, what is the Double Make/ Break Timer device?
1 Answer Nicholas, Yes, wires 1-6 are to the motor. 1 and 2 are going thru the centrifugal switch to the heater. TM is the timer and refers to a specific switch on the timer. And the double line break simply supplies voltage to more than one line on a setting instead of having 10 wires to the timer. Read More...
Nicholas December 13, 2018 for Model Number wp3399640 I tested my dryer's resistors for my dryer selector switch, same model number on my dryer and same model number part on my dryer selector switch, and they're both a little low but fit in their tolerance levels, so they're both OK. Is there anyway to test the selector switch for continuity by itself, like how many ohms would the selector switch be and where on the switch would you place the two leads?
1 Answer Nicholas, You would need to check the wiring diagram and see which terminals go to which setting whether no heat, high, med, low. Then you would set to that setting and test the switch for continuity. Read More...
Nicholas December 11, 2018 for Model Number WP3399640 I just checked my dryer's voltage. My dryer, model #WED5560SQ0 still has 240 volts and everything is still going smoothly. Is the selector switch supposed to have continuity on all 4 settings and why would the high setting still not heat up and dry even if the dryer still has 240 volts flowing through it?
1 Answer Hello Nicholas, the switch should read 5100 ohms on the pins that are separate from each other; the pins closest to each other should give you 910 ohms. Make sure you are getting 240v to the heater, you could be losing 120v that comes through the motor switch. Hope this helps! Read More...
Nicholas December 07, 2018 for Model Number WP3399640 Thanks for answering my selector switch question. I'd like to know a few more about the selector switch for my Whirlpool dryer model #WED5560SQ0. Should all the settings going from Heavy Load to Delicate have continuity on each one, including the heavy/ high load setting? Is the selector switch very important when it comes to drying clothes? And why would the dryer run on Heavy/High load and not have continuity?
1 Answer Nicholas, Yes the dryer would still run when set to the heavy/high load even though there is not continuity, it would just cause it not to heat. Read More...
