Nomenclature Model Number P P 9 75 B M 1 BB Product Color B = Black S = Black Glass W/Stainless Trim W = White Brand P = Profile Configuration P = Cooktop Engr. Revision Model Year Designator Feature Pack Designates Features - the higher the number, the more features Mini Manual Nomenclature Tag The nomenclature tag of your cooktop is located on the bottom of the burner box. In addition to the model and serial numbers, this tag tells you the power ratings of the supply circuit for the cooktop.
Introduction The new electronic cooktops make an eloquent statement of style, convenience, and kitchen planning flexibility. The electronic touch controls are simple to understand and easy to operate–just read and touch.
Installation Electrical Requirements GROUNDING SPECIFICATIONS Ground Path Resistance 0.10 Ω Max. Insulation Resistance 250K Ω Min. POWER SUPPLY REQUIREMENTS The cooktop must be connected to a supply circuit of the proper voltage and frequency as specified on the nomenclature tag. Wire size must conform to the National Electrical Code or the prevailing local code. The nomenclature tag is located on the bottom of the burner box.
There must be 5 inches minimum vertical clearance between the cooktop bottom and any combustible surfaces. Dimensions and Clearances The following MINIMUM clearance dimensions must be maintained. 13″ MAX. Depth of uprotected overhead cabinets 2″ MIN. Clearance from cutout to side wall on the right of the unit 30″ MIN. Clearance from countertop to unprotected overhead surface 5″ Min. Vertical Clearance 15″ MIN. Height from countertop to nearest cabinet on either side of unit 2″ MIN.

Using the surface elements. Your new Profile Cooktop makes an eloquent statement of style, convenience, and kitchen planning flexibility. Whether you chose it for its purity of design, assiduous attention to detail, or for both of these reasons—you’ll find that your Profile cooktop’s superior blend of form and function will delight you for years to come. The touch controls give you precise control of the surface elements.
ON/OFF Single Surface Element To turn on a single surface element: Touch the ON/OFF pad, then touch the (+)/(-) pad. To turn off a single surface element, touch the ON/OFF pad again. Use the (+)/(-) pad to choose the desired power setting. The control will beep each time a pad is touched. ON/OFF Dual Surface Element To turn on the surface elements: Touch the dual surface element ON/OFF pad, then touch the (+)/(-) pad. When the indicator light next to the pad is on, the large surface element is on.
Using the surface elements. ON/OFF Warming Zone Surface Element (on some models) To turn on the warming zone surface element: Touch the warming zone ON/OFF pad, then touch the (+)/(-) pad. Use the (+)/(-) pad to choose a setting of H (High) or L (Low). To turn off the warming zone surface element, touch the ON/OFF pad. Use only cookware recommended for top-of-range cooking. The WARMING ZONE will keep hot, cooked food at serving temperature. Always start with hot food. Do not use to heat cold food.
Operation Overview DIGITAL CONTROL SYSTEM The digital control system consists of 3 circuit boards: 1. The touch board (permanently adhered to the ceramic glass panel) senses user input, including control lockout, displays user settings, contains HOT lights and key touch beeper. It is the “Main” board for the system. 2. The relay power supply module (RPSM), located inside the drop box, provides DC for touch board communications and to relays controlling the heating elements. 3.

Cooktop Components WARNING: Before servicing the cooktop, power must be removed from the cooktop by turning the power off at the circuit breaker. WARNING: Sharp edges may be exposed when servicing. Use caution to avoid injury. Wear Kevlar gloves or equivalent protection. Glass Top Note: The ceramic glass top and touch board will be supplied as a complete assembly. If the touch board is damaged or defective, the entire glass top assembly must be replaced.
Daughter Relay Module (DRM) To replace the DRM: 1. Remove the glass top. (See Glass Top.) 2. Mark and disconnect wiring from the module. Note: The module is held in place by 4 retainers that lock the board in place using compression tabs. It may be helpful to remove the ink tube from an inexpensive ballpoint pen and place the barrel of the pen over each retainer to compress the tab. 3. Compress the 4 tabs and lift the module from the recess in the burner box.
Relay Power Supply Module (RPSM) If the RPSM is damaged or defective, it can be accessed by opening the drop box that is under the cooktop. Note: If the drop box is inaccessible, it will be necessary to remove the cooktop from the countertop. (See Cooktop Removal from Countertop.) Place the cooktop upside down on a protected surface. Note: The module is held in place by 5 retainers that lock the board in place using compression tabs.
To remove heating elements: Heating Elements The radiant heating element consists of a ribbontype resistance wire attached to the support insulation with molded ceramic walls in a corrosionprotected metal dish. On model PP975, the circular heating elements come in 5 sizes. 1. Remove the glass top. (See Glass Top.) 2. Mark and remove the wires to the element. 3. Lift the element off the springs. Note: When installing the new heating element, make sure the 2 springs are on the 2 posts.
4. Mark the numbers on the bottom of the element next to the tabs. 5. Remove the two ¼-in. hex-head screws and tabs. Install them on the new element in the same numbered position.

Element Resistance Troubleshooting WARNING: The power must be disconnected from the cooktop. The resistance of certain elements and the continuity of certain element circuit wiring can be tested without removing the cooktop from its installation. This test will aid the service technician in determining if the RPSM or the DRM should be replaced. This test assumes the touch board functions properly.
Element Hot Light Troubleshooting Each element's hot light limiter switch and its wiring can be tested without removing the cooktop from its installation. This test will aid the service technician in determining if the element should be replaced. This test assumes the elements heat properly. All circuits below element's glass top temperature of 150°F (66°C) should test open. If circuit tests 0 resistance, replace element.
