Are there any trouble codes displayed?
Ok I do not have the manual for this unit.
It is manufactured by Roper who is now owned by GE. GE is very stingy with their manuals unfortunatly.
If this just "happened" then I am afraid I will not be able to help you. I will opt out and hopefully another expert can assist you.
If there was something/anything that may have caused this that you can think of, please let me know, and we can go from there.
Best regards; The Home Smithy
Another expert contacted me and confirmed that it is time for a replacement. These units are no longer supported nor are parts available to repair them.
Thank you for the accept.
Im sorry it wasnt better news
