My tcl split ac works for 5 min, then gives e5 code.


E5 s a communication error between the indoor and outdoor units. It is stated in the service manual that the wiring between the indoor and outdoor has probably separated at one end of the terminal block. Most of the time however, it is usually a failure of either the indoor or outdoor electronic boards. A multimeter and knowledge of how to read "communications voltages is required. The machine will continually assess itself electronically to make sure all components are working properly. If after a given amount of attempts to communicate with the outdoor unit the machine still cant "talk" to the other 1/2 , it will show an E5 error and shut itself down. You could try switching off the power at the isolator or meter box for at LEAST 15 minutes and then turn back on to see if it resets. This sometimes works. Do not, just switch off and switch straight back on again.

Whirlpool Dryer Various Test Procedures - Part 1


TEST #1 Supply Connections
This test should only be done after confirming proper voltage at the outlet.
1. Unplug dryer or disconnect power.
2. Remove the cover plate from the back of the dryer.
3. Check that the power cord is firmly connected to the dryer’s wire harness.
4. Access the machine control electronics without disconnecting any wiring to the control board.
5. With an ohmmeter, check for continuity between the neutral (N) terminal of the plug and P8-3 (white wire) on the machine control board. If there is continuity, go to step 6. If there is no continuity, disconnect the white wire of the harness from the power cord. Test the continuity of the power cord neutral wire . If an open circuit is found,
replace the power cord. Otherwise, go to step 6.
6. In a similar way, check the continuity between the L1 terminal of the plug and P9- 2 (black wire) on the control board. If there is continuity, go to step 8. If there is no continuity, check the continuity of the power cord for power cord’s L1 wire. If an open circuit is found, replace the power cord. Otherwise, go to step 7.
7. Replace the main harness.
8. Visually check that the P5 connector is inserted all the way into the machine control electronics.
9. Visually check that the user interface assembly is properly inserted into the front console.
10. If both visual checks pass, replace the user interface assembly.
11. Plug in dryer or reconnect power.
12. Perform the Console Buttons and Indicators Diagnostic test to verify repair.
13. If indicators still do not light, the machine control electronics has failed: Unplug dryer or disconnect power.
Replace the machine control electronics. Plug in dryer or reconnect power. Perform the Console Buttons and Indicators Diagnostic test to verify repair.

TEST #2 Machine Control Power Check
This test is used to determine if power is present at the machine control electronics.
NOTE: The drum light is controlled by the machine control on all models.
1. Plug in dryer or reconnect power.
2. Open the door.If the drum light illuminates, then power is present at the machine control, and it is functional. Go to TEST #6. If the drum light fails to illuminate, do not assume the machine control electronics needs replacement. Several conditions may cause the drum light not to illuminate, including a bad bulb. If the drum light does not illuminate, go to TEST #1.

TEST #3 Drive Motor Circuit
This test will check the wiring to the motor and the motor itself. The following items are part of this motor system:
Harness/connection Belt/belt switch Drive motor Centrifugal switch Door switch Machine control electronics
1. Unplug dryer or disconnect power.
2. Access the machine control electronics and measure the resistance across P8-4 and P9-1.
If resistance across P8-4 and P9-1 is in the range of 1 to 6 ohms, replace the machine control electronics.
Otherwise, go to step 3.
3. Check the wiring and components in the path between these measurement points by referring to the appropriate wiring diagram and strip circuit in Section 7.
4. Check the belt switch and drive motor. Access the belt switch and drive motor by removing the front panel/drum assembly. Slowly remove the drum belt from the spring-loaded belt switch tension pulley, gently letting the belt pulley down.
5. Remove the white connector from the drive motor switch.
6. Check for the resistance values of the motor’s Main and Start winding coils. NOTE: Main and Start winding coils must be checked at the motor.WINDING RESISTANCE ω CONTACT POINTS OF MEASUREMENT
MAIN 1.4–2.6 Blue wire in back at pin 4 and bare copper wire on pin 5 of black drive motor switch
START 1.4–2.8 Blue wire in back at pin 4 and bare copper wire on pin 3 of black drive motor switch. If the resistance at the motor is correct, there is an open circuit between the motor and machine control electronics.
Check for failed belt switch. If the Start winding resistance is much greater than 4 ohms, replace the motor.
7. Check the belt switch by measuring resistance between the two blue wires while pushing up the belt switch tension pulley.If the resistance reading goes from infinity to a few ohms as pulley arm closes the switch, belt switch is OK. If not, replace the belt switch. If belt switch is OK and there is still an open circuit, check and repair the wiring harness.
8. Door switch problems can be uncovered in the Door Switch Diagnostic Test; however, if this was not done, the following can be done without applying power to the dryer. Connect an ohmmeter across P8-3 (neutral, white wire) and P8-4 (door, tan wire).With the door properly closed, the ohmmeter should indicate a closed circuit
(0–2 ohms). If not, replace the door switch assembly.

Precor 9.35 won't stay on.


you must replace the control board electronic.

Go to www.treadmilldoctor.coa5bb443a-9b01-48c9-9230-29270afbdc24.gifm

and get it see the diagram how the control board control almost the 80% of the machine.

God bless you

A maytag mah3000waa front load washer when it is started it runs for about ten seconds then stops. push start again it runs another ten seconds and quits again. it also does this in spin. could this be the...


The service manual says do this:

Runs For Five Seconds Then Shuts OFF:

Suspect a communication problem between
motor, the motor control board and the machine control board. Check the motor and
motor control system by removing the JP4
connector on the motor control board. Set
the timer dial into the delay cycle and then
press the push to start switch. If the motor
operates and the washer goes into a 50 rpm
tumble, then the source of the problem is the
RD 30 wire leading from the motor control to
the P4(2)/RD30 connector on the machine
control board. When the machine control
tells the motor control to run the motor, it
monitors the red wire to determine if the motor is actually running. If the board does not see a return signal, the washer will shut down.
If RD30 wire is making contact, then suspect
possible problems with timer input circuits



Tumbles Only:
When the door lock mechanism is in the
"locked" mode, the wax motor has extended,
forcing the latch axle to engage the door lock
enable switch. This ensures the door is fully
locked and the switch can then complete the
signal back to the machine control board indicating
the door is locked. Check connector
P3(7)/YL 36 wire to verify if the terminal is
making good contact to the board terminal.
Check the door lock enable switch for continuity
when the button is depressed. Replace
door lock mechanism if necessary.

IT appears to be inputs and not the control board.

If you need more assistance just repsond here and I will reapond accordingly.

Thanks for using FixYa.

Fridge gets cold then shuts off


Feel the motor temp. after letting it do its thing for a reasonable period. If motor is extreemly hot then it means motor is switching off on internal protection.(has to be replaced then.). Set temp to its coldest then see if it still switches off as it is. if the same, board is more likely to be a problem. Very seldom if ever does one have to replave sensors. (assuming it has an electronic board). If using a th/stat, replace it if temp does improve but still eratic.

The standard warranty on appliances is two years, contact Whirpool at (866) 698-2538 to check warranty status.


Regarding the motor, the motor is tested by energizing it directly, and reading volts from MCU (motor control unit) or timer control board.

Here diagrams and parts for your model.

Call Whirpool first.

Washer will not spin


Electronic motor needs to be reset. Unplug for 2 minutes, plug back in, open and close lid slowly 7 times to reset computer. Also check to see if belt is not broke, pull up top, remove front cover, just lifts off, check belt.

I assume you checked the belts to see if any cogs were stripped of of the belt. If ok, then I wuld suspect the brush roll motor, it is any inexpensive part and doesn't take much for it to fail. Undo the top so you can get to it and unhook the belt and see if it still shuts of, if it does, ten replace it, it it doesn't, then there is a problem with brush rolls or belts.

Wash motor fault


We got the same problem 2 weeks ago. Overode it by swiching everything off and then back on, wish we hadn't as te machine stopped washing 1 week later. Motor has gone $300 and it took the electronic controler out as well $300. Labour $100 plus call out $95. It'sa serious falut and should get it fixed which begs the question why have fault indicator ro this problem if you cna overide it. In addition you probbaly have a minor water leak from above the motor, which can be fixed with silicone. Asko saya it's machine lasts 20 years, think again as for a $1900 machine very disappointed.
