The dryer was drying, and suddenly stopped and control panel says call technician. Then says door open, won`t start after unplugging to reset it. The inside light stopped working at that time.

Timer.

Check the heater coil for opens or shorts.

Hey friend, thank you for your post!

From my understanding the panel on your Electrolux dryer is blinking and will not dry. It sounds like a potential problem with your control panel or sensor. I would perform a reset on your appliance which you can do by unplugging the power cord or flipping the household circuit breaker off for ten minutes.
If you continue to experience the lights blinking on your display the control panel or sensor may need to be replaced and I would recommend seeking assistance from a professional service technician for proper exchange of electrical components. -Matt

Do you have an error code displayed ? If so what is that. If not the either the door switch is faulty or the control board. More likely to be the door switch but, strange things do happen.Here is the door switch number 134813601. If you need help installing or more info let me know.

What happens when power comes back on

If it does this in a Timed Dry setting the timer is bad. If it does this in an Auto dry setting it could be a bad moisture sensor or a bad timer.

You are getting moisture in the control panel buttons. After a while the panel will not function at all. The light in the dryer tub will still come on when the door is open. When you unplug your machine and it sets for awhile you are allowing the moisture to dry and the machine can reset. Some people use a hair dryer to dry out the control panel for a temporary fix. Eventually, you will have to get it replaced once it stops resetting for you.

Not starting can be a door switch problem. Maybe when you removed the cover, something came unplugged. Flame suddenly stopping can be a sooted or dusty flame sensor. They do go bad, too. See if it can be bypassed for a test ONLY.

If this is a problem that when you push the start button the unit runs, but as soon as you release the button the unit stops, then I have personally experienced this. It's a problem associated with the microcomputer board inside the control panel. You will need to unplug the dryer first. Then open the control panel and inspect the circuit board for burned components.

Front Panel lights not working? Dryer inside light does work? I fixed this twice already on my dryer. Please read this whole explanation I live in New Orleans where the humidity is very high. I have a laundry room where my Washer and Dryer reside. Kenmore HE4T. I noticed that when I shut the laundry room door, my central A/C pulls hot air from outside the house via the dryer exhaust duct. This causes moisture to build on the inside of the dryer and especially the front control panel. Did you ever see moisture on your dryer?s door even when there were no clothes in it? The moisture collects on the Silicon board that controls the dyers function and basically causes a short. This is what I do to fix it. You will need a ¼ nut driver or socket. 1. Confirm that you have power to the dryer <- is the inside dryer light on when you open the door. YES- keep reading.. NO ? find the circuit breaker and reset it. 2. UNPUG THE DRYER! ! ! ! ! ! ! ! 3. Find the 3 screws in the back of the dryer that hold the dryer lid on. Unscrew them and slid the lid back and lift off. Is there moisture on the inside of the lid? 4. Find the 2 screws that hold down the front control panel. They should be silver and will be on top. Do not remove the inside gold screws. 5. Find the 3 screws that hold down the power control panel on the top left side of the dryer. Probably has a high voltage warning sticker on it. 6. Lift the power control panel (sheet metal) part and move it to the right so it lays on the dyers drum. There are some wires attached to it and unless you are a very handy person, I wouldn?t remove them. 7. Lift the front control panel straight up until it comes out of the dryer. There should be some wires that attach this piece to the power control panel. If you are handy, you can remove these 2 clip-on wires from the power control panel by squeezing the black connector locking clip and releasing it from the panel. 8. If you flip the control panel around you may notice moisture on the green silicon chips. Get a hairdryer and take your time to dry them. 9. Dry all components of the dryer with a hairdryer. 10. Put everything back together except for the lid and all the screws. Remember that the front control panel slides down first and then the power control panel sits on top second. Plug the dryer in and see if you get lights, but don?t start the dryer. Unplug the dryer and replace all the screws and the lid. The problem is that once the dryer gets wet from the moisture, it never dries enough for it to start working again. This is a bad design from Sears/Whirlpool. I learn my lesson that just because its more expensive doesn?t make it more better. I now keep my dryer and washer door open all the time even when there are no clothes in it. This lets the moisture escape into the house rather than collect in the dryer. I hope this helps at least one person. Thanks Jason Kennedy from New Orleans
