Hi John,
First try blowing back up the drain lines. A plastic tube that probably ends in the drip tray under the fridge. a dropped pea of some other debris can plug them.
after that it could be a lot of things but all more difficult. Defrost timers or heaters etc.
Good luck. Dan...[/QUOTE If that doesn't work, I take hair dryer and thaw the tube out. It probably is iced up. Been there and done that.
