Testing Procedures

!WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power to oven before servicing, unless testing requires power.

Component Testing

Illustration					Component	Test Procedure		Results
					Oven light socket	Remove one wire from receptacle and	Indicates continuity with bulb screwed in.
						test resistance of terminals
						..............Measure voltage at oven light	120 VAC, see wiring diagram for terminal
							identification.
							If no voltage is present at oven light,
							check wiring or light switches.
4-turn					Coil elements	Remove element and measure	Continuity, if not replace.
5-turn						resistance across terminals	4-turn:	37 to 45 Ω Approximately
(Model MER6555AA*)							5-turn:	23 to 27 Ω Approximately
1200 W					Ribbon elements	Remove element and measure	Continuity. If not, replace.
2500 W						resistance across terminals	1200W: 45 to 49 Ω Approximately
							2500W: 20 to 24 Ω Approximately
2400 W/1100 W (Dual)					Ribbon elements	Remove element and measure	Continuity. If not, replace.
2700 W/1700 W (Dual)						resistance across terminals	1100W: 40 to 46 Ω Approximately (Inner)
(Models MER6775AA*,							1300W:	47 to 54 Ω Approximately (Outer)
MER6875AA*)
							1700W: 30 to 36 Ω Approximately (Inner)
							1000W: 53 to 59 Ω Approximately (Outer)
2700 W (Single)					Ribbon elements	Remove element and measure	Continuity. If not, replace.
(Model MER6755AA*)						resistance across terminals	2700W: 19 to 23 Ω Approximately
100 W (Warmer)					Ribbon elements	Remove element and measure	Continuity. If not, replace.
(Models MER6775AA*,						resistance across terminals	100W: 132 to 146 Ω Approximately
