CAUTION: Electrical Shock Hazard!
Before attempting to reset the hi-limit thermostat, unplug the heater power cord
from the power source and from the heater.
WARNING!
Only use "non-metal" tools to depress the reset button.
Do not bypass or alter the thermostats in any way.
1. Remove the power cord from the wall outlet or power supply and remove the
other end from the front of the heater.
2. Open the door, reach into the compartment and hold the heater firmly while
you remove the 5 SS screws with washers, holding the heater against the inner
face of the module.
3. Place the heater on a stable surface with the metal section facing down.
Locate the small round hole in the cover with the word RESET next to the hole.
4. Using a small diameter, round, non-metal item such as a rigid plastic stir stick
or wooden skewer stick, guide it through the hole and depress the button on
the hi-limit thermostat as seen in the figure below.
NOTE:
The Amber light will not be active when the high-limit thermostat has
been tripped along with the loss of the heater element.
5. Remove the item you used to depress the button and re-attach the heater to
the module with the screws and washers.
6. Plug the cord into the heater and then to the power source. Switch on the
heater and verify it is heating up to the normal temperature.

VI. Care and Maintenance (continued)
Modules should be cleaned when they look dirty or as part of a preventive maintenance schedule
to ensure performance of the cart.
Place cart against a wall or have a helper hold the module in the back so it doesn't fall.
1. Put the cart's brakes on and make sure unit is unplugged.
2. From the inside of the cart, carefully remove 4 SS screws and washers at the corners from the module.
3. Gently push module from the inside and remove from cart.
4. Clean components and module with a moist soft cloth and mild detergent to remove dirt and grease.
5. Completely air dry all components or wipe with dry, clean soft cloth before re-assembling and using.
6. Carefully place heater into the recessed area of the inner face of the module. Align AC inlet for power
connection with rectangular hole through the module.
7. Use 4 shorter SS screws and washers to re-attach the heater to the module. Tighten the screws firmly
but not excessively.
Do not use tools other than a #3 Phillips screwdriver.
8. Reinstall module to the cart with the 4 SS screws.
9. During normal operation, periodically check screws for tightness.
10. Inspect plug blades and cord, place cord If frayed or blades or prongs are missing bent or broken.
Instructions for Resetting Heaters
NOTE:
Normal operation of the heater is controlled by an automatic cycling "Control Thermostat." Failure of the control thermostat may cause the temperature inside the
compartment to rise to temperatures that could cause damage to the plastic.
A second, manually resettable "Hi-limit Thermostat," is built into the heater circuit. This device will shut off power to the heater in the event the temperature in the cabinet
reaches to 195˚F (90,6˚C). The heating unit will not return to normal operation until the reset button on the hi-limit thermostat is depressed. Other factors can cause the
hi-limit thermostat to shut off power, such as fan failure or placing food pans inside the compartment with temperatures higher than 190˚F (87,8˚C).
