  If your Despatch oven is heating up slowly, it could be due to several factors: * The oven is improperly loaded. Try reducing the load or redistributing it within the chamber. * There is low line voltage. Ensure sufficient power and proper connections, and check for circuit overload. * Heating elements are burned out. Replace any burned-out elements. * A 240-volt oven is connected to a 208V line. Raise the line voltage to 240 volts or modify the oven for 208V operation (consult factory). * Fan motor failure. Replace the fan motor.
