if needed. Fuses, 10 Amp, motor and controls Check, replace if necessary. Fuse holder Check, replace if necessary. Hi-limit thermostat, Oven cavity Terminals are normally closed. If open, reset thermostat and retest. If thermostat will not hold for maximum oven temperature, and oven is not exceeding temperature setting, check for proper location of capillary bulb in its spring holder. If the capillary checks okay, replace the hi-limit thermostat. Switch, main power Check continuity between switch terminals. Replace switch as needed. Relay, oven start Check for 120VAC supplied to coil of relay. If no voltage is present, trace wiring back to main power switch. If voltage is present, check for pull in of relay contacts. Replace relay as needed. 20 minute time delay Check for 120VAC at terminal #1 to neutral on time delay relay. If voltage is not present, trace wiring back to 10A. fuse. If voltage is present at terminal #1, check for 120VAC at terminal #2 to neutral. If no voltage is present, and oven start relay is closed, replace 20 minute time delay relay. Relay, main fan Check for 120VAC to coil of main fan relay. If no voltage is present, trace wiring back to 20 minute time delay relay. If voltage is present, check to insure that relay contacts are closing. Replace relay as needed. Main fan motor Check for supply voltage at motor. If no voltage is present, trace wiring back to main fan relay. WITH POWER OFF: Check for opens, shorts or grounds. Turn fan blade to check for locked rotor. Capacitor Check for shorts or grounds. WARNING: Capacitor has a stored charge, discharge before testing. No main fan cool down 20 Minute time delay Check for 120VAC at terminal #2 to neutral while the oven is ‘on’. Turn off the main fan switch, 120VAC should continue to be present for 20 minutes. If voltage is not present for approx. 20 minutes, replace the 20 minute time delay. Oven fan relay Check for 120VAC to relay coil, if no voltage is present, trace wiring back to 20 minute time delay. If voltage is present, be sure that relay contacts stay closes during the 20 minute cool down. Impinger II – Advantage Digital Express Service Manual - Domestic Replace relay as needed. Main fan runs after 20 minute cool down Oven start relay Contacts should open when main power switch is turned off. Replace relay as needed. 20 Minute time delay 120VAC at terminal #2 should discontinue approx. 20 minutes after main power is switched off. If the oven start relay contacts are open, and the voltage continues at terminal #2 of the 20 minute timer, for more than 20 minutes, replace the 20 minute time delay. Oven fan relay Check to insure that the relay contacts are opening after the relay coil is de-energized. Replace relay as needed. 20 Minute time delay NOTE: On/ off operation of the main power switch will set the timer to 20 minutes. If the timer is accidentally reset, turn off the main circuit breaker for 15 seconds to cancel. No control box cooling Incoming power Check circuit breakers, reset if required. Check power plug to be sure it is firmly in receptacle. Measure incoming power, call power co...
