Page 5: Cem Cooktops
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Cooktop Models CEM Cooktops The CEM cooktops are mechanical models with a ceramic top and control knobs. The single radiant elements are controlled by the 1-cycle infinite switches. The dual elements are controlled by the 2-cycle infinite switches. The bridge element is controlled by a 2-cycle infinite switch and a relay (together they ser ve as a gang switch).
Page 6: Cet Cooktops
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Cooktop Models CET Cooktops: The CET cooktop has a touch sensitive mono-control system. By touching the pads on the ceramic top, you select the mode of operation and the desired power level. The electronic touch control board interprets the selection and activates the single, dual, triple and bridge elements.
Page 7: Cep Cooktops
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Cooktop Models CEP Cooktops: The CEP cooktop incorporates all the features of the cet cooktop plus zone smart. Z one smart senses the presence of cookware and selects the most appropriate sized element. Additionally, it turns the element off when the pan is removed.
Page 8: Ceramic Cooktop Technical Overview
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Technical Overview Ceramic Cooktop Technical Overview The CEM/CET/CEP cooktops are comprised of the following components: Radiant Elements Single Elements D ual Elements Triple Elements Radiant Bridge Elements Infinite Switches 1-Cycle 2-Cycle Control Knobs Relay Board Electronic Touch Control Relay Board Pot Sensing Circuit Board H eat Limiters Sensors...
Page 9: Component Description
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Component Description Radiant Elements A single element, illustration above, uses a wire ribbon that is located under the glass ceramic surface to provide the heat for cooking. The single element uses 1 wire ribbon. Radiant elements are designed to cycle on and off.
Page 10: Radiant Elements
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Radiant Elements The triple element, illustration above, uses 3 wire ribbons to provide heat for cooking. There are 3 ribbons within the same heating area. You can select the inner, the inner and middle, or the inner, middle and outer elements.
Page 11: Infinite Switches
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Infinite Switches There is 2 types of infinite switches. 1-cycle, and 2 cycle. The 1-cycle infinite switch controls the single element. The 1-cycle has an infinite number of heat settings between the low and high positions. D etents are found at low and high to define minimum and maximan heat settings.
Page 12: Relay Board
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Relay board A relay board and a 2-cycle infinite switch are used to operate the bridge elements. The bridge element (4000 watts) draws 16 amps at full capacity. The 2-cycle infinite switch is rated at about 10 amps. The relay is wired in series with the infinite switch and the bridge element.
Page 13: Temperature Limiters
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Temperature limiters Each element uses a temperature limiter to prevent the element from becoming too hot. The limiters have 2 sets of contacts, one is normally open, and one is normally closed. The normally open contact closes and turns on the hot surface light when the glass is too hot to touch.
Page 14: Component Description
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Indicator lights There are two indicator lights on the ceramic cooktops. The O N indicator light turns on whenever any element is turned on. The light remains on until all the elements are turned off. (see illustration) Each element features a hot indicator light circuit to show when the cooking surface is too hot to touch.
Page 15: Sensors
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Sensors: O n CEP models the sensors detect pan sensing and pan sizing. Pan sensing: The CEP models have sensors under the glass that detects if there is a metallic pan sitting on the element. The element will not heat if it is turned on without a pan present, or if the pan is removed from the element when it is operating.
Page 16: Component D Escription
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Pot Sensing Circuit Board The pot sensing circuit board works with the electronic touch control board to sense the presence and the size of a pan on the burner. Heres how it works: The input board sends a signal to the sensor in each of the elements. W hen a pan is placed on the element,the sensor sends a signal back to the input board.
Page 17: Component Description
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Electronic Touch Control Board The electronic touch control board is a microproccessor based control. It is comprised of 2 components, an input board, and a relay board. These 2 components are fastened together with stand off clips. There is a mylar sheet sandwiched between the 2 components.
Page 18: Relay Board
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Relay board The relay board has snap relays, a step down transformer, a microproccessor chip and several zenner diodes. The stepdown transformer receives 120 v.a.c. and steps it down to 12 v.a.c.. The zenner diodes rectify the 12 v.a.c.
Page 19: Component Description
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Component Description Input board The input board has three functions. First, it accepts mode and setting selections by the user. Second, it commands the relay board to perform the selected functions. And third, it outputs a signal voltage circuit to the element sensors to determine the presence of a pan , and the size of the pan.

Page 38: Pot Sensing Calibration
https://appliancetechmanuals.com CEM/CET/CEP Service Manual Pot Sensing Calibration Pot Sensing Calibration CEP models have the “Z one Smart” (Pot Sensing) feature, and must be calibrated, or recalibrated, whenever the Electronic Control is replaced. To calibrate the cooktop, the “P7” Menu must be accessed, followed by the “P8” Menu. A set of calibration plates, each having a specific size, weight, and material, must be placed on their appropriate element locations during the calibration procedure.
