Question about Frigidaire GLEQ2152ES Electric Dryer
I am suddenly getting an F40 error code on my dryer. I have vacuumed, unplugged, reset GFI, etc., to no avail. What does this code indicate, and how can I fix it? Do I HAVE to call for service? Thanks for your kind response.
I had this same issue. My dryer would run and heat up but then stop and give me the f40. I measured all thermisters and everything was in range. The tech sheet stated that I needed to buy a new control board and I did. Same problem.
The solution was a loose connection on for p4. I took needle nose pliers and squeezed the connector to make it fit tight on the board and everything is working now.
Bottom line, expensive dryer with cheap connectors.

F40 is a error that appears between the machine control and the motor control when communication becomes lost. Check the connection between the two. The error codes whould be on the tech sheet beneath your console panel along with how to check for this error. Contact service they should be able to give you more information

Had same problem. checked everything the machines "tech sheet" said to check. after no luck, called Sears and purchased the $190 service agreement. Tech came out, told him everything I had already done, he checked the Thermal Fuse located on top of the blower housing just below the drum, it was blown, replaced it ($39.00 part) and plugged the dryer back in and it worked! Fuse was blown and the Tech Sheet makes no mention of it as a possible problem with the F40 code. save your money, check the Thermal Fuse. Part No. 3390719

I just had and fixed this problem with my Elite Oasis dryer with F40 codes. My model does not have separate machine and motor control boards just the machine control board. I eliminated the thermal fuse as the problem. What I had to do is build up the edge connectors on the machine control board for P4 with solder to give the P4 plug a more secure fit. After doing that no more F40 codes. Before doing that beating the user interface or unplugging the power would work But after I had taken the P4 plug off several times in troubleshooting the fit was even more sloppy and that no longer worked. Be sure not to bridge adjacent connectors with too much solder.

What I found was a fuse in the control panel it was a 4amp it was blown its connected to the thermistor the black wire that goes to the thermo fuse it connected to the motor control board

Before you waste a penny. over the years i usually get an F1 code, this time i got an F40. what happens is the vibration from the dryer loosens the connectors on the pane.l twice I've had repairman here under a home warranty plan usually when the washer acts up because it doesn't cost extra to have them check both. twice they changed the control box which probably costs the warranty company a lot of money. unplug the dryer. loosen the three screws in the back that hold the control panel cover on the top of the machine. pull forward and take it off and lay it on the machine, the wires are long enough. pull off and reset the connectors pushing them in tightly, particularly the ones on the left control module. the right one is probably fine, its usually the left one. plug the machine back in and test. if that don't work try the right panel plugs. now, these are the modules on the top of the machine, i have never touched anything in the cover you take off. it will probably be fine until they get loose again. maybe one month, maybe six months maybe never. i'm not a repairman, just a Do it yourselfer

The F40 error code indicates a communication failure between the main machine control board and the motor control board for the blower motor on the dryer.
This can be caused by a loose wiring connection or a blown fuse.
