FEATURED MODEL ABOUT THIS TECHNICAL SERVICE GUIDE - FEATURED MODEL The new XL44™ series of gas ranges encompass over 40 different models. We have selected one model which covers most of the new features and designs reflected in the XL44™, 30" gas series of ranges. For model specific information, refer to the charts included in this Guide, on pages 8 & 9. This service guide will focus primarily on the NEW changes introduced in the XL44™ series of ranges.
A FULL RANGE OF POWER YOU DON'T COOK SPAGHETTI THE SAME WAY YOU SAUTÉ MUSHROOMS. You don't want a sauce to boil when it's supposed to simmer. For best results, different foods should be cooked over differing levels of heat. That's why, on GE gas ranges, each burner has its own BTU rating. The high-output burner provides quick heat-up and boiling—faster than the “high-power” burners found on most gas ranges. This burner supplies the intense heat needed for the lobster pot, pasta pan, or wok.

Other Leading Manufacturers' Average Amana, Magic Chef, Whirlpool, Maytag, KitchenAid, Tappan Maytag Whirlpool GE TRUETEMP,™ THE MOST ACCURATE OVEN IN AMERICA! The guesswork is gone. The temperamental oven is a thing of the past.
ONLY GE GAS RANGES HAVE AN APPETITE THIS BIG THE LARGEST USABLE OVEN CAPACITY IN 30" FREE-STANDING MODELS* There's more oven space inside the GE 30" free-standing gas range—room for an entree and four casseroles, with space to spare. For baking, you have the flexibility of using as many as six racks, or as few as you wish. QuickSet touchpad controls make it easy to set the oven temperature and baking or broiling time.
WE' VE PUT A NEW SPIN ON A GRATE TOP THE FIRST THING YOU NOTICE IS THE STRIKING DESIGN. A bold, geometric pattern tops off this GE gas range, but there's more to the cooktop than its beauty. The big story here is convenience. The cast-iron platform, made up of two interlocking grates, provides a flat surface for cooking and meal preparation. To switch cookware from one burner to another, you don't have to lift the pans, perform a balancing act, and risk spilling the contents.

CONVERSION TO LP (PROPANE) GAS 1 Convert Regulator - Regulator is located in the lower, left hand rear corner of the range as viewed from the front. Depending on the model, remove the storage drawer, broiler drawer or false panel to access the regulator. Some models with a broiler drawer will have a metal cover over the regulator that must be removed for conversion and reinstalled when conversion is complete. 2 To Convert - remove the large hex-nut which is located in the center of the regulator.

ERC III SPECIAL FEATURES The "SPECIAL FEATURE" modes can only be activated while the display is showing the time of day clock. These special features remain in the ERC's memory until you or the consumer change them. When the display shows your choice press the START pad. The special feature you selected will remain in memory even after a power failure.
COOK AND HOLD The cook and hold feature keeps cooked foods warm for up to 3 hours after the cooking function is finished. To activate this feature, follow the steps below: Press the BAKE and BROIL HI/LO pads at the same time for 2 seconds until the display shows "SF". Press the COOKING TIME pad. The display will show "HLd OFF." Press the COOKING TIME pad again to activate the feature. The display will show "HLd On.
Temperatures shown in degrees F. performance does not come about by chance. It requires advaanced technology and innovative design. GE proudly introduces the TrueTemp™ System, which delivers consistently even oven temperature for exceptional cooking results -- making it the industry leader.
ERC FAULT CODE MEMORY TEST ERC FAULT CODE MEMORY DISPLAY Have you ever run a service call and been told by the consumer that their range displayed an "F" fault code and when you arrive the fault is gone (cleared by the consumer) and the consumer can not remember what the code was? Well there is now a way to "recall" the last four fault codes from the ERC memory.
ERC DIAGNOSTIC TESTS ERC ON BOARD DIAGNOSTIC TESTS This test allows the Technician to energize the bake and broil relays (listen for A click), use the ovens onboard temperature sensing and control system to measure oven temperature (sensor, connector and ERC diagnosis) and lastly it allows you to test keypanel input responses.
LOCK MOTOR CIRCUIT A 5 LOCK MOTOR CYCLE TEST - The lock motor cycle test allows you to run the latch assembly through one complete cycle of operation, testing motor operation and front & rear latch switch contacts. To perform this test, push and hold the SELF CLEAN key pad - make sure that the oven door is closed (light switch depressed). While depressing the SELF CLEAN pad the lock motor will run through a complete cycle.
