Narrative:
The #1 engine overheat light illuminated off and on along with the master caution light. All other engine conditions were normal. We suspected this was a false indication. I flew the airplane and told ATC; and told the first officer to accomplish the qrc. After the qrc; the light went out. We set up for a single engine landing; coordination with ATC; accomplishing a cabin advisory with the purser. After an uneventful landing; the light came back on steadily. We accomplished the qrc and checklists which had us shut the engine down; and blow both fire bottles. All other indications were normal. The light continued to illuminate. We asked for the fire equipment to examine the aircraft. They saw no smoke or sign of fire. I had made an announcement to the passenger as to the situation. We contacted dispatch and hooked up with a phone patch with maintenance. After consultation with everybody; we decided to taxi the aircraft to the gate.
