If low or zero voltage, replace power cord. If voltage is correct, check for correct voltage out of rocker switch. If low or no voltage, replace rocker switch. Wiring problem. Check all electrical connections for burns, discoloration or arcing. Replace all connections or components with damaged terminals. Replace all damaged wiring with the same (or higher) rated wire. Platen inoperative. To check platen: Use an Ohm meter to test resistance of the platen heater (disconnect 1 wire to isolate heater). Correct cold resistance for heating element of platen are as follows: 120 Volts, 1750 Watts - 7.8 Ohms208 Volts, 2550 Watts - 16.2 Ohms230 Volts, 1900 Watts - 26.5 OhmsVCT-20 only. The auxiliary heaters are 144.2 Ohms at 208V/300 Watts. Conveyor drive motor inoperative or incorrect conveyor motor installed in toaster. To check drive motor: 1. Measure resistance of motor coil. Replace motor if coil measures either open circuit or zero resistance. 2. Mark the drive motor sprocket and count the turns per minute. Correct drive motor speed is nine (9) turns per minute for VCT-20; three (3) turns per minute for VCT-25; one (1) turn per minute for VCT-50. Product is getting stuck or conveyor belts stop when product is toasting. Bun adjustment controls set incorrectly. Measure bun thickness and set bun adjustment controls correctly (page 9). Conveyor release sheet not clean or missing. Clean respective items. Refer to Maintenance Schedule (page 10). TROUBLESHOOTING (continued) Problem Possible Cause Corrective Action Product is getting stuck or conveyor belts stop when product is toasting (continued). Not enough voltage, defective power cord or rocker switch. Check receptacle for correct voltage. See Specifications (page 5). With unit plugged in and rocker switch on, check for correct voltage into rocker switch. If low or zero voltage, replace power cord. If voltage is correct, check for correct voltage out of rocker switch. If low or no voltage, replace rocker switch. Wiring problem. Check all electrical connections for burns, discoloration or arcing. Replace all connections or components with damaged terminals. Replace all damaged wiring with the same (or higher) rated wire. Conveyor drive motor inoperative or incorrect conveyor motor installed on toaster. To check drive motor: 1. Measure resistance of motor coil. Replace motor if coil measures either open circuit or zero resistance. 2. Mark the drive motor sprocket and count the turns per minute. Correct drive motor speed is nine (9) turns per minute for VCT-20; three (3) turns per minute for VCT-25; one (1) turn per minute for VCT-50. Conveyor drive chain loose, worn or broken. Loose motor drive sprocket. Check drive chain for kinks, broken or bent links or other damage. Check motor sprocket and drive sprockets (on drive shaft); tighten setscrew on flat of shaft if required. Check for damaged/worn sprockets and replace as required. Conveyor cover assy(s). not installed, or improperly installed. Install conveyor cover assy(s). Conveyor belts installed incorrectly. Install conveyor belt to match diagram in Fig. 8 (page 11). Be sure that ends of the hooks are facing down. Conveyor belt too loose or missing links (41 links required when new). When new, conveyor has 37 large links and 4 small links. Remove conveyor belt (page 11). Lay belt flat and count links. Replace entire belt if links are damaged. If conveyor belt has too much play, it will jam. Adjust belt length as described under Servicing the Conveyor Belt (page 11). Spring tensioner assy(s). or tensioner bent or missing. Replace spring tensioner assy(s). (29, page 22) or tensioners (4, page 24) if damaged or loose. Replace slide rails (40, page 24 worn or missing. TROUBLESHOOTING (continued) Problem Possible Cause Corrective Action Conveyor belts are “jumping” or “snapping”. Toaster is installed incorrectly. Perform installation and operating procedures (pages 7-9). Bun adjustment controls set incorrectly. Measure bun thickness and set bun adjustment controls correctly (page 9). Conveyor drive motor inoperative or incorrect conveyor motor installed on toaster. To check drive motor: 1. Measure resistance of motor coil. Replace motor if coil measures either open circuit or zero resistance. 2. Mark the drive motor sprocket and count the turns per minute. Correct drive motor speed is nine (9) turns per minute for VCT-20; three (3) turns per minute for VCT-25; one (1) turn per minute for VCT-50. Conveyor drive chain loose, worn or broken.
