Figure 34: Checking the bottom heater lamp contacts
Grasp the lamp (1) near the center. Push the lamp slightly
toward one contact block (2), then the other. You should
feel some movement in each direction as the contact
springs flex. The lamp should not rattle or feel loose. The
lamp should be supported only by the pins in the contact
blocks. Rotate the lamp a small amount, in both
directions, about its long axis to feel that the bulb is
securely seated on the contact pins.
