Section III: Service & Maintenance
Warning:
Always disconnect power before cleaning (or servicing)
the unit.
This section covers the basics of servicing and maintaining
your equipment. A “Maintenance and Service Log” is
included in this manual for your use in recording all
maintenance and service performed.
IMPORTANT: Service must be done by a qualied
technician experienced with commercial gas and electric
cooking equipment. Use only OEM supplied parts.
Unauthorized or generic parts can cause bodily injury and
equipment damage. If the unit ever needs repair during
the warranty period, prior authorization is required. A)
Replacing Primary and Secondary High Limit Thermostats
Servicing
Re-Calibrating Thermostats (Do Not Attempt)
IMPORTANT! If either thermostat is defective or not
working properly, it must be replaced (without breaking
the seal) and returned to Accutemp. The warranty is
voided if the seal is broken or any attempt is made to
recalibrate a thermostat. See below for replacement
instructions.
Replacing Primary Thermostat
1. Disconnect the unit from its power supply.
2. Remove the control console panel.
3. Disconnect and mark wire(s) connected to the normally
closed position with the enclosed tag marked normally
closed.
4. Disconnect and mark wire(s) connected to the common
position with the enclosed tags marked common.
5. Remove the thermobulb hold-down bracket, which
secures the thermobulb to the plate surface. Pull
thermobulb and capillary tube back through the access
port to remove the thermostat from the control console.
6. Remove the two mounting screws on the existing
thermostat from the front panel.
7. Use the existing hole locations for mounting the
thermostat. The two outer holes on the new thermostat
bracket are for mounting the thermostat and the two
inner holes are for mounting the bezel. With a marker,
mark the hole locations for drilling the bezel holes.
8. Drill holes through the front panel with the #32 drill
bit.9. Locate the new replacement thermostat on the
inside of the control box where the existing thermostat
is mounted. The thermostat should be mounted with
the at side of the dial stem facing the right side of the
unit and the common pole (“P” terminal) will be on the
left side. You will use the #6-32x1/4” round head slotted
screws provided to mount the thermostat in the two
outer holes.
10. After this has been completed, secure the bezel
in place with the #6 Type “F” x 5/16” pan head phillips
thread cutter screws provided in the two inner holes
which should have been drilled out in step 8. Note: The
triangular indicator marking on the bezel should be in the
3 o’clock position.
11. Reconnect the wires marked normally closed to
the normally closed position on the new replacement
thermostat with the piggyback push-on connector (if
more than one connection is needed) or a single push-on
connector (if only one connection is needed) as provided
in the installation package.
12. Carefully uncoil the capillary tube. Re-insert the
capillary tube and thermobulb through the access port
from which the old tube and bulb was removed and re-
install the thermobulb in the same location from which
the old thermostat thermobulb was removed.
13. Replace control console panel and secure in place.
Hi-Limit Thermostat Replacement
1. Follow steps 1 through 5 of the primary control
replacement procedure.
2. Remove the two mounting screws on the existing hi-
limit thermostat from mounting bracket.
3. Reconnect the wires marked normally closed to
the normally closed position on the new replacement
thermostat with the piggyback push-on connector (if
more than one connection is needed) or a single push-on
connector (if only one connection is needed) as provided
in the installation package.
4. Reconnect the wires marked common to the common
position (“P” terminal) on the new replacement hi-limit
thermo-stat with the piggyback push-on connector (if
more than one connection is needed) or a single push-on
connector (if only one connection is needed) as provided
in the installation package.
5. After wiring connections are complete, place the hi-
limit thermostat in the control console. Locate the new
replacement hi-limit thermostat on the mounting bracket
and secure in place using the 6-32x1/4” round head
