May indicate a fault with a heat sink temperaturesensor. The affected pan location is not availablefortimingproductandaqualifiedservicetechnicianshouldbecontactedtoidentifythecauseofthefault.
Temperature Check Procedure
1. No pans should be in wells during the pre-heat and temperature check. Pre-heat the warmer for 30 minutes before taking any temperaturereadings.Donottakereadings unlessthecavityhasbeenempty for30minutes. This will allow thetemperaturetostabilizeandwill preventfalsereadings.
2. A digital temperature meter that has beencalibrated must be used to get an accurate temperaturereading.Useathermocouplesurfacetemperatureprobetomeasuretemperatures.
3. Theheatingwell shouldbecleanedandemptybeforethetemperatureischecked.Avoidanyairdraftsthatmightflowthroughthecavity.
4. Locate the surface temperature probe on thebottomofthefirstcavityasshownforthecabinetsize.
5. All temperature controls exhibit a swing intemperatureasthecontrolcyclesonandoffwhileregulatingtothesetpoint.Thecorrectcalibrationtemperature is the average of several readingstakenoveraperiodof20minutesafterthewarmerhasbeenpre-heated.Theaveragetemperatureshouldbe±5°Ffromthesetpoint.

CLEANING & ROUTINE MAINTENANCECLEANING
IF DAILY CLEANING IS PERFORMED ROUTINELY, DEEPER, MORE AGGRESSIVE, CLEANING METHODS CAN BEAVOIDED. OVERLONGERPERIODSOFTIME,FRIEDFOODPRODUCTSCANACCUMULATEANDBAKEONSURFACESOFTHECOMPARTMENTS.
Cleaning solutions need to be alkaline based or non-chloride cleaners.Any cleaner containing chlorideswill damage the protective film of the stainlesssteel. Chlorides are also commonly found in hardwater, salts and household and industrial cleaners.If cleaners containing chlorides are used, be sure to rinserepeatedlyanddrythoroughlyuponcompletion.
WARNING: NEVER USE AN ACID BASED CLEANING SOLUTION!
MANY FOOD PRODUCTS HAVE AN ACIDIC CONTENT WHICH CAN DETERIORATE THE
FINISH. BE SURE TO CLEAN ALL FOOD PRODUCTS FROM ANY STAINLESS STEEL
SURFACE. COMMON ITEMS INCLUDE, TOMATOES, PEPPERS AND OTHER VEGETABLES.
Routine cleaning of stainless steel can be done with soap and water.Extremestainsorgreaseshouldbecleanedwithanon-abrasivecleanerandplasticscrubpad.Itisalwaysgoodtorubwiththegrainofthesteel.
