Star Manufacturing Conveyor Toaster Troubleshooting Toaster Cooking Equipment Guide

Star Manufacturing makes a variety of high-volume and compact conveyor toasters that toast everything from bread to bagels quickly. While these machines are renowned for their durability and quality, problems can still occur on occasion. If your unit isn’t working properly, this Star Manufacturing conveyor toaster troubleshooting guide will help you solve issues with ease.

This guide contains information for models such as the QCS1-350 and QCS1-500B. For more information on caring for your unit, see our article on how to clean a Star conveyor toaster.

Not Heating & Conveyor Belt Not Moving

When there is no heat and the conveyor belt won't move, check for the following:

  • Power cord unplugged – See if the unit is unplugged or the power cord is damaged. If the cord is damaged, have it replaced by an authorized technician.
  • Controls or circuit breaker off – Make sure the controls are switched to the ON position. Also, check if the circuit breaker is on. Reset if the breaker is off.

If issues persist, contact an authorized service technician to troubleshoot and repair the unit.

Heat Only on One Side, Conveyor Belt Turns Freely

If the conveyor moves freely but there’s only heat on one side, this typically means the heating element needs to be repaired or replaced. Contact an authorized service technician to resolve the issue. 

Conveyor Belt Turns At One Speed

If the conveyor belt only turns at one speed despite the speed control settings, the speed control might have to be repaired or replaced. Contact an authorized service technician to fix the speed control.

Conveyor Belt Is Stuck

When the unit heats up but the conveyor belt is stuck, look for mechanical binding following the procedure below:

  • Step 1. Shut off unit – Turn off the conveyor and unplug it from the wall outlet.
  • Step 2. Open bottom enclosure – Remove the holding screws on the bottom of the toaster. Set the toaster on its legs and remove all four screws on the back of the unit. Then, slide the enclosure off and remove the back panel.
  • Step 3. Move the drive motor – Unfasten the four screws holding the drive motor. Once loosened, slide the motor upward. This lets you remove the drive chain from the unit's sprockets.
  • Step 4. Check for binding – Check for mechanical binding by moving the conveyor belt by hand. If the belt moves freely, this could mean the drive motor or speed control needs to be repaired or replaced; if so, call an authorized service technician for service. 
  • Step 5. Close the enclosure – Slide the enclosure forward toward the front of the toaster. The enclosure's front edge will slide beneath the front of the unit.

If binding is present, contact an authorized technician to make any necessary repairs.

Product Sticking To Belt Or Slide

Whenever product regularly sticks to the belt or slide, it usually means that food is being prepared incorrectly. Please do the following to prevent sticking:

  • Toast food at room temperature – Never put products in the toaster that are frozen or straight out of the refrigerator; instead, bring them up to room temperature before placing them in the unit.
  • Don't add butter or butter alternative – Make sure whatever you toast doesn't have butter or a butter substitute on it.

When you accidentally toast frozen product or add butter or a substitute, the product might come out overly moist or doughy and stick to the machine’s interior parts. If this occurs, make sure to follow the cleaning instructions in the operator’s manual.
