7.The bayonet connector is spring loaded.. Turn the connector so that it makes good contact with its seat on the plate, and adjust the spring so that at least 1” (25mm) of spring is available to push home.. This is, it is loaded 1” (25mm) from the bayonet adapter..
8.Once this adjustment is made, remove the thermocouple from its cavity, pry the old heat sink material from the cavity and apply fresh heat sink compound (Garland Commercial Ranges part #77024)..

Incandescent Lamps
These lamps, similar in construction if not in shape to ordinary incandescent light bulbs, sometimes fail because of metallurgical breakdown of the light filament material.. The green status light (PL1) should illuminate when the main switch SW1 is closed..
•If PL1 doesn’t illuminate when SW1 is closed, replace it..
•Failure of the amber lights (PL3, PL4, etc..) monitoring the zones cycle with the thermostat is not easy to detect.. When on, an amber zone light is working.. If it does not appear to light as part of the ‘burner on’ cycle, check.. If the thermostat cycles the burner to be on, the PL amber light should illuminate..
Pilot Ignition Control (Control Module)
The Johnson G770 pilot ignition unit will lock out if the pilot flame is not sensed before the end of the ignition trial period and has to be reset..
•To reset the ignition control, turn off the thermostat for a minimum of 30 seconds..
