Fisher & Paykel DE08 Dryer sensor

My dryer has stopped sensing the moisture content of the clothes.

I'd like to know the part #, cost and location of the moisture sensor. And possibly the degree of difficulty for repair.

    i have the same problem. clothes go in, heats for a little bit, and then switches over to cool down and shuts off.

    I guess it's possible that the sensor wiring may be an issue, worth a check. I have also read that if your air duct is clogged there will be inconsistent results.

My guess is your PC Board (PCB) is shot and needs to be replaced. From the manual: The PCB measures moisture across the sensing bars on the front duct assemby (it is possible, but unlikely that the sensing bars have lint over them which may be causing a problem). As the clothes slide past the bars the PCB reads the current across the bars. When the clothes are dry the current ceases so the PCB advances the timer. There should be a min of 1 M ohm across the bars when dry. The resistance should be lower when mositure tracks across the bars. To test the bars check the resistance when dry, then wet your finger and place it across the bars and check for resistance. is very unlikely the bars are the problem. More likely it is the PCB. Part Number WE1M418 for the DE09 (similar to the DE08, but check to make sure with your local appliance parts person). How to replace the PCB: Open the console; unscrew and remove the PCB cover; disconnect the PCB connector; unclip PCB from its holding clips. Reassembly is the reverse procedure. NOTE: The PCB is NOT, repeat NOT, the timer!! It is located on the inside of the console on the left hand side of the instrument cluster

There is no heat, when i pushed the reset button it blew warm air for a few minutes. Now there is no heat again. What can i do, or what do i need to fix. Where is the heating element. I can't see it...

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.

Puddles of water forming under the unit

clean out the dryer and the vent line,you need to clean out the duct that the lint filter slides into,vac out the inside where the motor is and if the vent line is long blow it out with a leaf blower,also check the outside vent to make sure nothing is blocking it.the hot moist air isn't blowing outside,it's stuck in the dryer and vent line,all a dryer does is remove the moisture out of the clothes by moving air,if the air can't move correctly themoisture has to go somewhere.let me know how you make out,also if it's gas do this once a year,electric once every two years so you don't have a fire

Fisher & Paykel Auto Sensor Dryer stops & beeps constantly

Hi emkboyce

my Fisher Paykel auto sensor dryer keeps stopping and beeping, i have to stop it and and re start.

I had the same problem. I took it off the wall and vacuumed up all the lint from everywhere including around the back and including taking off the back and vacuuming everything I could reach inside. I then used a damp cloth to get rid of the rest of the lint/dust.

I thought I was wasting my time but guess what, the problem has gone.

Good luck!
