KitchenAid Microwave Error Codes: F1E4, F1E5, Door Error Guide

Quick Answer

KitchenAid microwaves are Whirlpool-manufactured and use identical error codes: F1E4 (power relay stuck - safety shutdown), F1E5 (humidity sensor fault), F1E6 (magnetron relay), F2E1 (keypad short), F6 (communication), and 'Open/Close Door' (interlock switch). Replacement parts cross-reference directly between KitchenAid and Whirlpool using the same part numbers.

KitchenAid microwaves are Whirlpool-manufactured and use identical error codes: F1E4 (power relay stuck - safety shutdown), F1E5 (humidity sensor fault), F1E6 (magnetron relay), F2E1 (keypad short), F6 (communication), and 'Open/Close Door' (interlock switch). The KitchenAid-specific difference is the premium door handle - heavier than standard Whirlpool, which accelerates door hook wear and makes the 'Open/Close Door' error more common on KitchenAid than on equivalent Whirlpool models. Replacement parts cross-reference directly between KitchenAid and Whirlpool using the same part numbers. KitchenAid Superba and Architect series use the same internal platform.
