PURPOSE: An operating time measuring apparatus for a heater, and an operating method thereof are provided to enable users to expect the oil usage amount of agricultural equipment. CONSTITUTION: An operation method of an operating time measuring apparatus for a heater comprises the following steps: detecting the voltage using first and second terminals of a sensor, and detecting the current flow on third and fourth terminals for determining the normal operation of a fan motor; detecting the IG input voltage change value on 11th and 12th terminals for determining the normal operation of an IG trans; detecting the voltage using fifth and sixth terminals, and detecting the current flow on 7th and 8th terminals for determining the normal operation of a fuel valve; calculating the resistance value change of a CDS photoelectronic sensor on 9th and 10th terminals using a separate circuit to determine the normal operation; and counting the time if all the operations are normal using the operating time measuring apparatus. |
