no defrost cycle

[ken brooks]

Can anyone tell me why my whirlpool refrigerator WILL NOT GO INTO
THE DEFROST CYCLE. Ice builds up in the freezer and slowly melts
into the frig. Main drain is not blocked.

Not without knowing the exact model of refrigerator involved so we can find out how it was designed. What is needed is its exact model number. If you post that information we'll see if we can make an educated guess.

You can find tips for locating the model and serial number identification tag on your appliances at the following link:

WILL NOT GO INTO THE DEFROST CYCLE.

What makes you think it is not "going into defrost" as oppose to just not defrosting when it gets there?

You can read how the defrost system operates on most frost free refrigerators at the following link:

Hello,
Thanks for your advice
Its a Whirlpool Gold model#GT19DXHWOO, Ser# EJ1817304 Made in1999
What I have done so far, is defrosted the frig,cleaned out the drain hole.(with hot water and compresssed air). Restarted frig, and still getting ice buildup in drain area.Ice is blocking off drain hole.The Ice will backup into the freezer and slowly melt into the frig, causing all the food to become wet.
Any ideas

Thanks ken

That appears to still be missing a letter as indicated above.

The fridge's defrost mechanism has nothing to do with the water getting drained. All it does is melt the frost off the evaporator (cooling) coil... which turns into that defrost water.

I have defrosted the frig, cleaned out the drain hole with hot water and compressed air.

Where is this drain hole you're referring to?

On a top-freezer refrigerator like I think you have, the area needing attention would usually be at the rear, ceiling of the refrigerator compartment. If you're going at it from the freezer compartment, you're quite possibly in the wrong area. You can see the usual problem area for several different makes and designs of refrigerators at the following link. Maybe one will give you an idea for your model?

What usually happens is as much water as it can pools in the freezer which then freezes. Any more water overflows and starts running into the other compartment. "Ice" in the freezer shouldn't melt.

Where is this drain hole you're referring to? Its at the back of the frezzer compartment. Theres a long melal tray with a hole in the middle for draining the defrost water from the evaporator (cooling) coil that's on the back wall of the frezzer compartment. The water is frezzing up the metal tray and plugging the drian hole.

Thanks for your advice

That's better. You can see exploded parts views of it at the following link:

this drain hole is at the back of the freezer compartment.

Than you're likely in the wrong area to correct the actual cause. On a top-freezer refrigerator like yours, the area needing attention would usually be at the rear, ceiling of the refrigerator compartment. When it backs up there it causes pooling in the drain trough beneath the evaporator (cooling) coil in the freezer compartment where it eventually freezes to ice.
