Hi and welcome to the site.
Would you please read the posting tips at the main page of the HVAC forum and then edit your post to include the info the techs will need. This will assure you a quicker response time.
I am also going to move this to the Service and Repair of Other Brands.
Thanks,
Yanita

Faulty reversing valve/rev. valve solonoid maybe.
Thanks,

You're very welcome. Just a guess from here, but since it reverts back to a/c mode for defrost, rev. valve/rev. valve sol. are in the act.
Refr. lines are connected to the valve, so I would look there first.
Take care and best wishes,
Robert
