Hi, welcome to Just answer
How old is it ?
probably 3 or 4 year old
OK, and how did the problem start ?
just doing normal drying on sunday (was working a few days before) didn't work. is it possible the sensor / thermal cutout cuts out at a much lower tempersture thsn it should ? can I bypass them just to see if they are faulty?
usually when all lights flash it is the thermal cut off that is bad however, as you have already checked it for continuity lets try to see if we can get any error code here
Can I remove it from the heater but leave it electrically connected and leave it just in room air to see if it works correctly?
to test it you have to remove it completely and then check it for continuity
Ok, I only put test meter across terminals while it was connected to machine, I'll remove wires and check it
oh ok ... similarly test the element after you have removed it and everything disconnected
Sensors both give resistance of 0.6 ohms. element does heat up but only for 10 seconds
and element has continuity after it is removed ?
ok then please follow this and tell me what you get :
Unplug the dryer and plug it back in after 2-3 minutes...once it is plugged back in PUSH and HOLD the START button ( make sure the dryer must be OFF and the door Closed while you are doing this) ....now while holding the START button turn the program selector knob to position #3.
After this is done...The Acrylic/Synthetic LED should come on and stay lit with fixed light....now release the START button and then PUSH and RELEASE it twice within 2 seconds...now it wil start the auto test sequence
For 3 seconds the LED will be lit and then the Buzzer beeps and display envision
All LEDs are lit fixed and the buzzer beeps once again...if there was any stored error code it will now come up...
Also all the LEDs will blink in a sequence to give a error, please count number of flashes between the pauses and let me know how many times it flashed
flashed 14 times
There was no buzzer though
OK 14 flashes indicate Rear NTC detected faulty
have you checked that as well for continuity ?
If it is on the top of the heater panel / unit, then yes I checked both sensors and they both gave 0.6 ohms
also check its wiring and connectors
All wiring seems ok and connectors are fine and firm fit
OK, and have you replaced the PCB or the control module ?
Yes ,yesterday I checked heater sensors etc and ordered control panel which arrived this morning. Yesterday there was no heating at all with the new control panel it heats for 10 s before cutting out
OK and you are sure the PCB was installed correctly and you had the machine unplugged when installing it ?
replaced the full PCB on front panel and carefully remove the connectors from the old one and made sure the went it the orientation on the new one, Is the control module on the pcb or is it separate ?
a moment please
you have already checked these two parts and they show continuity ?
and please check this video and confirm that; this is how you have tested these parts
The top picture is not the same as the one fitted, the bottom picture checks out ok
this is the thermal limiter
Have used multi meter to check parts, they check out ok and have also checked for blockages in vents
well I understand, I dont think it is anything else as the error code also indicate the problem with the Rear NTC, or its wiring or the connectors...the control board seems to be fine as it is new and I think even the old one is fine
as it has to do with the dryer not heating I will simply go ahead and release the NTC first and then the heater assembly
these elements are covered under 3 to 4 years of warranty however this should be checked with the manufacturer
also if there is a start relay on the motor for this model you can also test that after you take it off
Ok , thanks for you help. I'll spend a bit more time on it but think I,m going to have to buy a new drier.
You're welcome....You can get back to me if you need any assistance and I will help with no additional charges.....Excellent feedback is appreciated if you are satisfied with my assistance.... Good Day
Found out the Thermal Limiter fitted to outlet manifold (big plastic bit that has outlet tube / hose connected to it from the drum) has no resistance even when warmer with hairdrier. Think this has been problem.
