Hobart Rack Oven Troubleshooting Solutions

Burners Won’t Light

On Hobart gas rack ovens, check for the following if the burners aren’t lighting:

  • Oven was accidentally turned off – It’s common that someone accidentally turned the oven off. Double check that the ON button is turned on.
  • Door is open – Close the oven door, so that it’s sealed shut.
  • Gas valve is off – Turn the gas shutoff valve back to the ON position.
  • Oven needs to be reset – Sometimes, the unit needs to be reset. Simply press the OFF button and wait about five minutes to push the ON button.

Circulation Fan Runs with Oven Off

If the oven’s circulation fan is running when the unit is off, the oven likely has entered cooling mode with the door open. If the door isn’t open with the fan running, contact a local Hobart service technician to remedy the issue.

Rack Won’t Lift or Rotate

If the rack isn’t rotating or lifting, the bake time wasn’t entered in the timer or the timer wasn’t started. Resolve this by entering a time in the bake timer and pressing START. If the issue continues, contact a local Hobart service technician to resolve the issue.

Steam Timer Won’t Adjust Properly

If the steam timer isn’t setting above 10 seconds and the time increments operate by one second, the oven likely is Food Service Mode. Return to Bakery Mode by pressing and holding both the START and POWER ON/OFF buttons. Select Parameter 14 and set the value in the bake timer to “0.” The steam time will now work in five-second increments.
