Dryer problems


Do not rule out your control board but there are a couple of heat sensors you need to check. There is one bon the heat coil and one on the air exhaust. you can bypass them both one at a time to verify those are not it.

Whirlpool Dryer Various Test Procedures - Part 2


TEST #4 Heater
This test is performed when either of the following situations occur: Dryer does not heat Heat will not shut off
This test checks the components making up the heating circuit. The following items are part of this system:
Harness/connection, Heater relay, Thermal cut-off, Thermal fuse, High limit thermostat, Gas burner assembly,
Centrifugal switch, Exhaust thermistor, Machine control electronics, Gas supply. Dryer does not heat:
1. Unplug dryer or disconnect power.
2. Remove the back panel to access the thermal components.
3. Perform TEST #4b. If the thermal fuse is OK, go to step 4.
4. Perform TEST #4c. If the thermal cut-off is OK, go to step 5.
5. Locate the high limit thermostat. Measure the continuity through it by connecting the meter probes on the
red wire and blue wire terminals. If there is an open circuit, replace the high limit thermostat and thermal cutoff.
Otherwise, go to step 6.
6. Perform TEST #4d. If this is OK, replace the machine control electronics.
Heat will not shut off:
1. Unplug dryer or disconnect power.
2. Access the machine control electronics, remove the P14 connector, then measure the resistance between P14-3 (red-white wire) and P14-6 (red-white wire) at the connector. If 5–15 k ohms are measured, replace the machine control electronics. If the resistance is greater than 20 k ohms, replace the exhaust thermistor.
TEST #4a Exhaust Thermistor
The machine control electronics monitors the exhaust temperature using the exhaust thermistor, and cycles the heater relay on and off to maintain the desired temperature. Begin with an empty dryer and a clean lint screen.
1. Plug in dryer or reconnect power.
2. Start the Timed Dry cycle.
3. If after 60 seconds, F-22 or F-23 flashes in the display and the dryer shuts off, the thermistor or wire harness is either open or shorted. Unplug dryer or disconnect power. Check wire connections at the machine control electronics and thermistor. If wire connections are OK, check exhaust thermistor resistance per step 5.
4. If F-22 or F-23 does not flash in the display, the connections to the thermistor are good. Therefore, check the exhaust temperature value at any or all of the temperature levels in question, using the Timed Dry cycle, and the following process: Hold a glass bulb thermometer capable of reading from 90° to 180°F (32° to 82°C)
in the center of the exhaust outlet. The correct exhaust temperatures are as follows:
TEMP
SETTING HEAT TURNS
OFF* HEAT TURNS
ON High 155° ± 5°F
(68°± 3°C) 10–15°F
(6–8°C)
below the
heat turn off
temperature Medium 140° ± 5°F
(60°± 3°C) 10–15°F
(6–8°C)
below the
heat turn off
temperature Low 125° ± 5°F
(52°± 3°C) 10–15°F
(6–8°C)
below the
heat turn off
temperature Extra Low 105° ± 5°F
(41°± 3°C) 10–15°F
(6–8°C)
below the
heat turn off
temperature The measured overshoot using the glass
bulb thermometer in the exhaust outlet can
be 30°F (17°C) higher.
5. If the exhaust temperature is not within specified limits, or you have come here from step 3, remove the P14 connector, then measure the resistance between P14-3 (red-white wire) and P14-6 (redwhite wire) at the connector. If the resistance is OK, check P14-3 and P14-6 to machine ground. If resistance is greater than 0 (zero), replace wiring harness. NOTE: All thermistor resistance measurements must be made while dryer is
disconnected from power. The following table gives temperatures and ranges for the associated thermistor resistance values.
Temp
F C
Res
kΩ
Temp
F C
Res
kΩ
50° (10°) 19.0 -22.0 80° (27°) 8.5-10.5 60° (16°) 14.8-16.8 90° (32°) 6.8-8.8 70° (21°) 11.5-13.5 100° (38°) 5.0-7.0 If the thermistor resistance does not agree with table, replace the exhaust thermistor. If the thermistor resistance checks agree with the measurements in the table, replace the machine control electronics.
TEST #4b Thermal Fuse
The thermal fuse is wired in series with the dryer drive motor.
1. Unplug dryer or disconnect power.
2. Access the thermal fuse by first removing the back panel.
3. Using an ohmmeter, check the continuity across the thermal fuse. If the ohmmeter indicates an open circuit,
replace the failed thermal fuse.
TEST #4c Thermal Cut-Off
If the dryer does not produce heat, check the status of the thermal cut-off.
1. Unplug dryer or disconnect power.
2. Access the thermal cut-off by first removing the back panel. .
3. Using an ohmmeter, check the continuity across the thermal cut-off. If the ohmmeter indicates an open circuit,
replace the failed thermal cut-off and high limit thermostat. In addition, check for blocked or improper exhaust
system.

TEST #4d Gas Valve
1. Unplug dryer or disconnect power.
2. Access the gas valve by removing the front panel and drum assembly.
3. Use an ohmmeter to determine if a gas valve coil has failed. Remove harness plugs. Measure resistance across terminals.

Have power everywhere but won't turn on


see this causes and fix it. God bless you
1. No power to the dryer
Make sure there's power getting to the dryer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power with a voltmeter or by plugging something else in. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.

2. Door switch / Door switch actuator lever
The dryer would not start with a broken door switch. Replace the door switch if found defective.

Most dryers have a door switch actuator lever - when you close a dryer door, it presses against the lever, which actuates the door switch. If the lever is broken, the switch would not activate and the dryer would not start. Replace the lever, if broken.

Note: Door switch actuator lever usually comes with the door switch assembly and it is recommended to get the whole assembly since there is almost no price difference between the door switch assembly and just the lever. Check your model for more details.Thermal Fuse The thermal fuse helps to prevent a dryer fire by shutting off power to the dryer if it overheats. If the dryer won't start check this fuse first. Test the thermal fuse with an ohm meter or continuity checker. This is the most common part to fail when the dryer won't start. Once the thermal fuse has blown, it has to be replaced. It can not be reset.

Thermal Cut Out Fuse Kit Most dryers have several temperature control devices such as a thermal fuse, thermal cut out, high limit fuse or high limit thermostat. Some manufacturers sell the thermal fuse and thermal cut out in a kit. These kits normally solve no-heat problems rather than when the dryer won't start. However, in some models, this kit will solve both problems. Even though this is not the most common part to fail if the dryer won't start, both can be checked using an ohm meter or continuity checker. If they have continuity they are good. If not, they should be replaced.

Main Control Board The main control board is normally not at fault when the dryer won't start. First, check all of the other components in this troubleshooting guide before replacing the main control board. The main control board can not be tested and must be replaced if it is defective. If there are obvious signs of burning or a shorted out component on the board, it should be replaced.
Timer The timer is normally not at fault when the dryer won't start. In many situations where timers are replaced they end up being returned. First, check all of the more common components in this troubleshooting guide before replacing the timer. If the dryer won't start, the cause is much more likely to be a thermal fuse or switch. The timer can not be tested, it must be replaced if it is defective.

My gas dryer burner does not heat. The igniter does not glow even to permit the gas valve to turn on. Everything else works and checks out being good, such as the thermostats, igniter, flame sensor. ...


You could check the igniter by testing to see if 120 volts is at the wiring the igniter plugs into, if 120 vac at that plug the igniter is bad Also need to check THERMAL FUSE,in addation to thermostat,on electric dryers if thermal fuse is out it cuts circuit to motor, on many brand dryers if thermal fuse bad on GAS dryer it cuts circuit to igniter

Model 110 73932101 kenmore elite. Blew the circuit board replaced it and checked the relays. Wont heat, found the thermal fuse is blown. Checked the high limit thermostat and the thermistor. Thermistor...


there is thermal fuse, Hi limit, and thermistor. the thermistor should have continuity at room temp I don't know what resistence(ohms) it should have. Most units I have seen provide a schematic and trouble shooting guide taped under the control panel for service personal.

Model 11-85862400: Check Lint Screen light blinking and will not start. Cleaned sensor and all bottom inside of dryer. Will not start.


Disconnect power and remove the two screws from the bottom flange of the toe panel then pull the panel down and off the cabinet.

Remove the screw from the lint duct bracket and remove the bracket. Remove the two hex-head screws from the lint duct and remove the duct.

Remove the wires from the terminals of the thermal fuse then join them together and insulate the connection properly.

Reconnect power then press start. Replace the thermal fuse along with the thermistor if the dryer starts. The thermal fuse is wired in series with the motor and if it is blown, power to the motor is terminated and will not run. No dryer function works when the motor doesn't run. The thermal fuse usually blows due to failed thermistor or blocked lint screen or vents. This is the reason the "Check lint screen." message flashes.

Disconnect power, if the dryer still doesn't start, then remove the top panel and check if the belt is still on. The belt activates the belt switch which is also wired in series with the motor and the thermal fuse. The motor will therefore not run if the drive belt is off and the belt switch is not activated.

Check the wire connections on the electronic control board. The electronic control board has indeed failed and needs to be replaced as what the Sears repairman said. The electronic control board is part number 8546219 and it costs about $180.

Maytag neptune dryer won't start has power lights will come on but ut won't run flashed PF before it quit


Hello & Welcome to FixYa

PF error code means power failure and is displayed when the circuit board also known as the electronic control board goes bad and needs a replacement. Before replacing the control you can also check the thermal fuse which is inside the rear panel on the blower wheel housing and replace if it reads no continuity. Please get back to me if you have any other questions.

Dryer wont start when button is pushed.the thermal fuse was tested (good) the high limit thermostat was replaced as with the thermal cutoff. I did notice an abnormality on the cap of the electronic control


Did you check the door switch? Electronic control could be an issue but start with the basics and you have covered most of them already... good job.
