Is it a must to have this part? Without it will the watertank freeze? Mine accidently got thrown away. Thank you, Stan
Answer Hello Stan,
You may want to order on to put in the unit. This part is used to prevent the water tank from freezing. If it freezes, it will have to be replaced since the expansion of the ice will split the tank and cause water into the bottom of the unit and will put water into the floor.
