ABSTRACT OF THE DISCLOSURE A control system and programmer/timer for a microwave oven having a program cam advanced by a pawl-stepped ratchet wheel having three toothed segments, each with teeth of differing root diameter. The outer teeth provide rapid expanded scale advancement for the terminal five minutes of the cooking program and also for selected programs of five minutes or less for high-resolution switching by the program cam. The segment of teeth of intermediate roof diameter provides a compressed scale slower cam advance rate for "COOK" programs of 5-35 minutes. The segment of teeth of lowest root diameter provides slow rate cam advancement for auxiliary "DELAYED START" and KEEP-WARM functions where time accuracy is not critical. The programmer/timer enables continued advancement of the program cam after time-out of the cooking program where the KEEP-WARM mode has been preselected.
