In some cases it is desirable that the lights work the other way around. To do this you have to change the wiring of the Quartz lights. Below is described how to do this with the different rotisseries. See also the circuit and wiring diagrams. TG 110 M: Change the wires 36+M2 on the Quartz light on customer side with the wire 33 on the Quartz light on service side. TG 330 and 550 M 3~208V: Change the wire 23 on the main switch with the wire 25 on the connection block. Change the wire 24 on the contactor with the wire 36 on the connection block. TG 330 M 1n~208V: Change the wire 24 on the contactor with the wire 36 on the connection block.

AnAlyTIC TROUbleShOOTInG lIST SERVICING AND REPAIRING Of ThE TG110/330/550 M This is an analytic description for servicing and repairing all major parts of the rotisseries and war- mers. It consists off 4 basic steps to recognize and solve the problems. These steps are: 1. Symptoms. 2. Possible causes. 3. Solving of the problem: checking/action. 4. Replacing of parts and testing. a. Replacing is described in the service manual. b. for testing see programming of rotisserie on page 5 in this manual. Description of part Symptoms Possible causes Solving: checking/action Door broken glass Slamming of door. Give instruction to operator. fastening bolts and nuts are loose. Tighten all fastenings. Door adjustment Door not well adjusted and Adjust door on hinge and closes against bottom side. tighten the hinge plate. heating element Rotisserie doesn’t reach adjusted temperature Wiring. Check the wiring. Check the power on the element. Element malfunction. Check the current with AC current tester. See table on page 24. Duration of grilling time is too long Wiring. Check the wiring. Element malfunction. Check the current with AC current tester. See table on page 24. Thermostat Contactor doesn’t come in after starting of program Wiring. Check the wiring. Thermostat malfunction. Check if the thermostat is making contact. Contactor switches off be- fore reaching the adjusted temperature in program Thermostat malfunction. Check if the safety ther- mostat on the inside is turned fully clockwise (con- tact closed). Thermostat probe not in right position. Check the position of the thermostat probe. Main switch no power to all, or some oven controls Wiring. Check the wiring on the switch. Malfunction of the cams on the switch. Check the cams. Contacts burned. Check the contacts on the switch.

Description of part Symptoms Possible causes Solving: checking/action Timer no functions of oven are working Wiring. Check the wiring on the switch. Check the power on the switch. Malfunction of the timer. Check functions after con- necting a new timer. Grilling process is working, but doesn’t stop Malfunction of the timer. Check if the time is running down on timer (does it tick). Check if the timer switches off after reaching the zero position. Contactor Contactor doesn’t come in Wiring. Check the wiring. Coil malfunction. Check resistance of the coil. This should be ±525Ω. Contactor comes in, but one or more functions from the switch don’t work Contact burned. Check the wiring. Check the power on all contacts. Check the contacts of the switch. Capacitor Drive motor or blower doesn’t work Wiring. Check the wiring. Capacitor malfunction. Check function after con- necting a new capacitor. Checking of capacitor: Discharge capacitor with screwdriver. Set meter on MΩ and connect the pins of the meter on contacts, value runs up. Change the pins on contacts, value runs up again. This means the capacitor is OK. Another test is to charge the capacitor with a Meg- ger on 250V and first check the insulation value. Wait for a minute and discharge the capacitor with a screw driver. When it still flashes it means the capacitor is OK.
