Whirlpool WP2321805 Refrigerator Defrost Thermostat OEM Part

Ordered and replaced defrost timer and bimetal defrost switch. Defrosted the freezer coils. Got to timer on top of unit. Removed timer. NO instructions with new timer!! Ohmed new timer to figure what the loose timer wire tied to. Compared to schematic and decided on connecting it to 2 (pink). Put it all together along with the bimetal switch. Checked continuity of heaters. Seemed to be cooling properly but could not hang around for a defrost cycle. Will check again soon to see if the ice is building again. Took a few hours but was a satisfactory experience.
