LED panel shows code 8.8. . I cannot find this code listed anywhere . Any ideas ? maytag neptune dryer mde5500ayw ?
I think anything Maytag made with the word Neptune on it is pretty much a problem machine. See if you can clear out the error code. If not, I think it means your main control board has malfunctioned and will need to be replaced, but with unless you can put it in diagnostic mode you will have to replace it on speculation.
Here is a Service Manual

and here is a correction on the service manual, which may be applicable, check your serial number

and here is tech bulletin on a change in the control board which may or may not be applicable in your situation.

I’ve been experiencing the same code 8.8. problem in my Maytag Neptune electric dryer for many months now (Model MDE5500AYW), but have been able to clear the issue by placing a hot water bottle on the face of the control panel–until this week. Now, I have to blast it with my wife’s hair dryer for about 10 minutes before it will come out of its coma.
I was unable to open the servicematters service manuals, but found the same thing here. The service check came out perfect, including the membrane switches, and there were no diagnostic codes recorded. It appears the control panel is faulty but responds to external heating. Sounds like a bad solder run on the circuit board, but how to find. Has anyone been able to repair the board when this problem is experienced, or does everyone just buy a replacement board?
Maytag support disavows any knowledge of this problem, despite numerous reports on the web from others. If the replacement boards are fixing this problem, it seems like Maytag should share the cost with us, but so far, no luck.
Thanks!
Thanks for the post. It does sound like a hairline crack in the connections on the board, almost impossible to find.
Maytag has punted on a lot of problems with various machines.
Thanks again for your post, it is very helpful.
When the hair dryer/heating pad trick fails to work…try replacing capacitor 15…it might have a slight bulge on the top of it. I replaced mine and haven’t had an issue since.

I know this thread is old, but it seems to be helping people still! I see that 20 people have viewed the photo, so there are many of us trying to figure this out. I just finished replacing the drum bearing on the washing machine a month ago and now the hair dryer trick isn’t working as well as it used to. (This has been going on for about a year, but only when it’s somewhat cold. These units have been a pain, but they’re too expensive to give up on!
Tracbulit, can you share with us where you bought that capacitor? I would love to give that a try before replacing the whole control board (which is the only other solution I’ve seen besides yours. )
Thanks you!!
It has been quite a while since you replaced the Capacitor. If you still have the
machine, is it still working? Please advise. Thank you
Had same issues with the 8.8 code - took the control board out and indeed the C15 capacitor had a slight “bump” on it - the previous comment pointing to this as a root cause made troubleshooting a lot easier 
Replacing the cap fixed the problem.
The C15 cap is a 3300uF (microFarads) and is rated at 16V - the package is 12.5mm (i think). The cap is either an input or an output capacitor for the DC-DC regulator.
Since so many people are having this issue my guess is that the engineers did not choose proper voltage rating or ripple current rating; if doing the repair I would suggest going with a 25 or 35V part of same capacitance in industrial temperature rating of 105 or 125C.
Some parts that will work:
EEU-FC1E392L ; UPW1E392MHD.
Note the direction of the white line on old and new replacement part - they must face same direction while installed on the board.
The whole repair can be done with a cheap soldering iron, flux, and some solder wick for cleaning out mounting holes.
It is worth to note that the 8.8 error is not actually a code - that’s why no one knows about it. 8.8 on the display is simply all LED lights being on at once due to low DC voltage going to the main controller on the circuit board - caused in this case by the C15 going bad.
Hope it helps!
Used the hair dryer trick. Got “code” to delete and various numbers to show, but still won’t start. Ideas?

Neptune show 8.8 error dryer will not start. Some how I figured out if I press Time Dry button then panel show 40 min then press + button to change time to 41 min then press Start like magic it starts!! then reset panel to sensor setting and reset temperature setting, and Very Dry setting it works have been doing this for about a year now.
Had the same problem with Maytag Neptune Dryer not turning on and getting “88” on the display. Thanks to the great posts here and the troubleshooting diagnostics I was able to fix my dryer and make my wife extremely happy! No more sticking the heating pad on the front panel and waiting for hours for the dryer to turn on. After years that became less and less helpful and would have to wait several hours with the pad to turn the dryer on. Not anymore. I replaced the c15 capacitor which I new was bad as soon as I saw it (bulge at top and leaking). I changed it out with a higher voltage rating of 35v (the original was 16v), and kept the same 3300uf and temp rating of 85C. The capacitor at Frys Electronics (part #6432852) was $2.69. It was much bigger than the original but it fit. The only thing I wasn’t ready for was the amount of glue that was holding the capacitor and the one next to it to the board. I imagine it was for vibration. I re-glued the new capacitor in with glue gun like the old one for anti-vibration. After a little heat with a heat gun and some isopropyl alcohol I was able to pry enough away and desolder old capacitor out. Fingers crossed this holds up since the repair was just done. Thanks to the information here it saved me hundreds of dollars.
This forum helped me fix my Maytag Neptune Dryer. I replaced the C15 capacitor with a new 3300uf 25V (the old one was 16V) that I picked up from the local Fry’s Electronics in Phoenix, Arizona, and it worked great!
The resistors on upper right side of my control board have obviously been giving off a lot of heat over the years, and have browned the board, and the back of the white plastic, but they still work fine as far as I can tell.
Thank you!

No buldge, but sucess un c15
Unplug machine. Peel the control PAD plastic from the right a few inches. Remove the metal triangle at the start switch. Clean metal triangle and area it goes into with rubbing alcohol. Press plastic pad back.
Went to an electronics store, bought a soldering iron kit. Then, removed the c15 capacitor and replaced it with a 3300uf 25v capacitor (the old one was 16v but you can use a capacitor with higher voltage).
The machine started working. As a previous poster mentioned, my resistors were also browned and you could see it around the board. However, they seem to be working fine.
Still a valid topic, 9 years on.
Same problem: 8.8. showing in the Maytag Neptune electric dryer display. The fix is replace the 3300uf 16v capacitor on the board. I’ve done board repairs on all kinds of industrial stuff, and had one on hand. Fifteen minutes from start to finish.
FWIW, the resistors R53-R56 are metal film 820 ohm, 5% (stripes: gray, red, brown, gold), probably 5 watt. Mounting them further from the board would have alleviated the burn on the upper right. It may not be an issue for the life of the rest of the dryer, but if I was engineering the board for long term use, mounting them on 1/4" (6mm) legs would be better.
Thank you for sharing your repair experience with us.

Thanks! changing time to 41 worked brilliantly!
My Neptune dryer stopped working as well with an 8.8 error code displaying right after I plug it in. You push start and it does nothing.
Then I just tried the above solution of pressing Time Dry, setting the time to 40 min, then setting it to 41 min and pressing start. Sounds illogical and insane but it worked! Thanks!
With error 8.8, I rest pressing (Damp Dry) Button and (time -) Button at the same time and works again.
Thanks
