Is the thermistor bin the sensor along the side of the compartment that sences when the ice is low?
Yes, the bin thermistor is the j shaped tube that is on the right wall of the icemaker that senses the level of ice in the bin.
I think I have a faulty bin thermistor for my model. My question is. Can I use a whirlpool part # 2217288 instead of my models' part #WR55X10545? They look exactly the same and the grid they plug into, along with the connector, looks exactly the same, only diff is the price it seems. Thanks.
Answer Jonathan, the two thermistors do not cross reference or replace one another and we will not be able to verify that your can use the Whirlpool in replacement of the GE thermistor. The thermistor called for your unit is WR55X10545. You may try the part and return it if it does not work on your appliance, here is the link to our return policy for you to view, thanks! http://www.appliancepartspros.com/customerservice/returns.aspx
