Our Kenmore Elite Oasis dryer model #11067087600 has stopped working and flashing code F40. I checked the internet & this website for possible answers as to what the F40 code means and what can be done about it. We tried the troubleshooting possibilities with no luck. I then called Sears customer service and explained the situation, and was told that the F40 code means the electronic control was damaged and needs to be replaced. Also, this is something that can be done by us and no repairman needs to come to the home. So the part was ordered and delivered after a few days. My husband replaced the control, but it did not work either, and it's still flashing code F40. My husband called Sears customer service again and after speaking with a few different people, including a service tech, he was transferred to a service parts dept rep, Katy, who was extremely rude stating no one told us to order any parts and a service tech needs to come to our house, which will cost about $120.00, just to check the dryer and then tell us what the problem is. My husband was speaking with a service tech before Katy, and he asked to be transferred back to a service tech but she refused to do so and told him to come onto this website to ask questions. We didn't understand what's the difference in speaking with an actual person then and there, vs getting on the internet and asking the question online and having to wait for someone to get back to us. This has become a frustrating situation and Katy is the first person we've spoken to who has refused to assist us. We hope someone else can. Thank you for your time.
I understand that you are getting the error code F40 on your Kenmore Elite Oasis dryer. I have taken some time to research your question here on the Manage My Life website and I noticed that someone else had asked a similar question with a posted response from an expert. I attached the link below for you to view. I hope the link that I provided is helpful. Have a nice day.
I apologize for all of the trouble that you have had while addressing this issue. I will do my best to help you get this situation resolved.The F40 does indicate that you have a communication error between the main machine control board and the control board that governs the blower motor in the bottom of this dryer. This is sometimes caused by a failed control board but often it can be caused by a loose wiring connection as described in that link for a previous answer that Alina F. posted in the above response. It can also be caused by a blown thermal fuse. This is probably the most frequent cause of the F40. I recommend that you check that issue first. The first image below shows a diagram of the components in this dryer. The second image shows how to open the cabinet and access the thermal fuse. Be sure that you unplug the dryer before accessing internal components. The third image shows a wiring diagram with the wires going through the thermal fuse and then to the motor control board highlighted in blue. Here is a brief video that shows how to check that thermal fuse using a volt/ohm meter: Video: Thermal Fuse Testing . (If you don't have a volt/ohm meter, you can normally buy one at your local Sears store or hardware store for around $20 or less.) This information should help you check that issue. If that thermal fuse is blown, it will need to be replaced. The part number for that thermal fuse is 3390719. NOTE: Check the exhaust vent duct system for a clog as shown in that video if the thermal fuse was blown .If that thermal fuse is okay, I recommend that conduct the tests shown in the 4th image below for that blower motor (with the dryer still unplugged ). A problem with that blower motor can cause the F40 code. One other problem that can cause the F40 code is an internal wire harness fuse in that wiring that is highlighted in blue on the third image below. If the above tips don't help you find the cause of the F40, I recommend that you check the continuity in that wiring between the P9-1 connector on the main machine control board (blue wire) and the MC1-4 connector on the motor control board (black wire). Be sure that you still have the dryer unplugged during this test. The resistance through that wiring should be near zero ohms (continuity) if the thermal fuse is okay. If it is open (measures infinite resistance or ol -- Open Load) then that wiring harness will need to be replaced.I provided the access information for the control boards in the 5th image even though you probably already have that since you replaced that control board.This may be a large amount of technical information to digest. If you have any questions or need more help, reply with additional details and we will assist you further.I appreciate your feedback regarding the problems that you had with our service. I will pass that along to our managers. I hope that we can make this right. I am confident that we can. If a control board was not needed for this repair, I am sure that we can arrange for you to return that component.
