A method and a system for automatically ordering replacement of consumable parts of a system. At least one parameter for a part of the system is monitored. The parameter is compared to at least one replacement criterion. A user notification is automatically generated when a comparison of the parameter to the replacement criterion indicates that a replacement part should be ordered. Responsive to a user input or an automatic system control, a replacement part order is automatically communicated to a replacement part order center. The monitored parameter can be a duration of operation, an output level, an input level, an operating temperature, a number of on-off cycles, an oxidation level, a corrosion level, a decomposition level, or a material elasticity level. The order can be transmitted to the replacement part order center through a global computer network, a cable television network, a wireless link, or a dial-up telephone line.
