COMPONENT REPLACEMENT  
1. Remove the access panel on the left side.  
2. Remove all screws holding down the cover.  
3. Lift cover straight up.  
Replacement of the voltage regulator, actuating switch, main terminal block, or the contactor (1048  
only) will require removing the component mounting plate.  
1. Disconnect the wires from the on pilot light and the switches.  
2. Tag or mark the wires to ensure correct replacement.  
3. Remove the two mounting screws.  
One is located at the bottom left of the voltage regulator.  
The other is located under the lower part of the cooling fan. This screw can be reached  
through the blades of the fan.  
4. Remove the component mounting plate and replace the component. Make sure that the screw  
that operates the actuating switch is above the switch lever.

TROUBLESHOOTING  
(See component location drawing on page 4.)  
WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND  
FOLLOW THE LOCKOUT / TAGOUT PROCEDURES.  
IF THE UNIT BLOWS A FUSE OR TRIPS A CIRCUIT BREAKER  
1. Check the capacity of the circuit.  
2. Short circuits may be accompanied by sputtering sounds or sparks.  
IF THE HEATERS DO NOT LIGHT  
1. If the pilot light does not come on, and the cooling fan does not run, check for a blown fuse or  
an open circuit breaker.  
2. Check for failure of the main switch.  
3. On the 1048, check for contactor failure.  
4. Check for a loose wiring connection.  
5. If the pilot light is lit, and the cooling fan is running, but the heaters do not light, check for loose  
wiring connections. When the cheesemelter is operating in standby with no product on the rack,  
the heaters may not glow, but will still emit some heat.  
6. If one heater is lit, but the other is not, a burnout or a loose connection is the probable cause. Also,  
check that the heater is properly seated in its socket.  
IF THE COOLING FAN DOES NOT RUN  
1. If the pilot light is not lit, and the heaters do not light, check for a blown fuse or open circuit breaker.  
2. If the pilot light is lit and the heaters function, the probable cause is a loose connection.  
IF THE HEATERS DO NOT COME UP TO FULL HEAT WHEN THE PRODUCT IS PLACED ON THE  
RACK  
1. Be sure that the product is on the front half of the rack. The rack is balanced to trip the actuating  
switch, but the weight must be on the front half of the rack to ensure that it does so.  
2. Check that the rack is at the same level on both sides and is correctly inserted.  
3. If the rack operates freely, the failure of the actuating switch is the probable cause.
