The problem is probably the starter asm. on the compressor, though it could be signs that the compressor is failing. An amp draw test would be a good place to start
Put a bright flashlight inside freezer then close the door. Cut all lights off and see if you see any light leaving through the gasket. If so it could be gasket or it could be that the door is not closing properly.
The water line shut is usually behind the unit.Pull it out from wall. Just turn clockwise to shut the water off. Depending on your model you can turn the ice maker off by letting up the handle in the ice tray.That shuts it off from making ice.Newer models have a button on door that reads ice off.But if it's leaking water.Shut water off and left handle up or ice off at door. That way it's not trying to make ice.
get one from any fridge service shop
be prepare to pay that as the glass in the bulb is special pyrex glass to withstand the extreme cold and normal bulbs are not suitable for the job
Hello, Suzanne -
Most ice makers in refrigerator / freezers have a heavy metal wire "arm" which activates and deactivates the ice making process. When the "arm" is in the down position, ice is made.
With most refrigerator / freezer ice makers, the "arm" can be set in the up position, so that the ice making process is stopped.
