If the mechanical timer in your Vulcan-Hart Convection Oven is inoperative or not functioning properly, the possible causes are: * Interconnecting wiring malfunction. * Incorrect line voltage. * Timer malfunction.
Why is my Vulcan-Hart VC4ED Convection Oven not heating?
Your Vulcan-Hart Convection Oven might not be heating due to: * A high limit switch being open. * A temperature probe malfunction. * A computer control malfunction.
Why is my Vulcan-Hart VC4ED cooking unevenly?
Uneven cooking in your Vulcan-Hart Convection Oven can be caused by: * Convection fan motor speed/direction issues. * Missing or damaged air flow baffles. * Incorrect line voltage. * Malfunctioning heating element(s). * Contactor malfunction.
What to do if my Vulcan-Hart VC4ED has excessive or low heat?
Excessive or low heat in your Vulcan-Hart Convection Oven may be due to: * Incorrect line voltage. * Heating element malfunction. * Contactor malfunction. * Convection fan motor malfunction. * Temperature probe or mechanical thermostat malfunction. * Temperature control not calibrated. * Temperature control malfunction.
What to do if my Vulcan-Hart Convection Oven has no heat but the convection fan motor runs?
If your Vulcan-Hart Convection Oven's convection fan motor runs but there is no heat, the possible causes are: * The high limit thermostat is open. * The heating element is malfunctioning. * The contactor is malfunctioning. * The temperature control is malfunctioning.
Why does my Vulcan-Hart VC4ED high limit thermostat keep shutting off the heat?
If the high limit thermostat in your Vulcan-Hart Convection Oven is shutting off the heat, it could be due to: * A temperature probe malfunction. * A computer control malfunction.
What does Er03 mean on my Vulcan-Hart VC4ED?
An Er03 error code on your Vulcan-Hart Convection Oven indicates an ambient sensor error, potentially caused by the ambient temperature being below 32 F. Check the ambient temperature at the control.
Why is there no power to temperature control on my Vulcan-Hart Convection Oven?
If there is no power to the temperature control on your Vulcan-Hart Convection Oven, it could be because: * The power switch (S1) is in “Cool Down”. * The door or door switch is open.
Why doesn’t the blower motor run in “Cool Down” but runs ok in “ON” position in my Vulcan-Hart Convection Oven?
If the blower motor in your Vulcan-Hart Convection Oven doesn’t run in “Cool Down” but runs ok in the “ON” position, it may be due to: * Power switch (S1) malfunction. * Fan speed switch (S3) malfunction. * Interconnecting wiring malfunction.
Why won't the blower motor run on my Vulcan-Hart VC4ED when the power switch is in the 'ON' or 'COOL DOWN' position?
If the blower motor doesn’t run with the power switch in the “ON” or "COOL DOWN” position on your Vulcan-Hart Convection Oven, the possible causes are: * Incorrect line voltage. * Power switch (S1) malfunction. * Fan speed switch (S3) malfunction. * Solid sate relay (SSR) malfunction. See \"SOLID STATE RELAY TEST\" under \"COMPUTER CONTROL\" in the manual. * Interconnecting wiring malfunction. * Motor inoperative. * Computer control malfunction. See \"COMPUTER CONTROL OPERATIONAL TEST\" in the manual.
