Product: Commercial Mircowave Oven

Model: NE1257R, NE1258R, NE1757R,

NE2157R, NE2180, NE3280

Subject: Magnetron Test for Opens, shorts or Insufficient Power

A. The following tests will indicate if a magnetron is open or shorted.

•Unplug the unit

•Discharge all the H.V Capacitors (refer to service manual on how to discharge)

•Disconnect all the leads (connectors) from the magnetron terminals.

B. The following temperature test will indicate if a magnetron is weak. Make

sure unit is plugged in.

1. Fill a beaker or cup with EXACTLY 8 oz (1 Cup) tap water.

2. Record the temperature of the water (Should be approx. 70oF)

3. Place it in the center of the microwave and heat it for the time specified*.

4. Water should be boiling. Record the temperature again.

5. Temperature should rise approximately 142oF (Go to Step 6 only if temperature rise is

considerably lower than 142oF otherwise all magnetrons are functioning properly)

6. To test for the weak magnetron, connect one magnetron at a time and repeat Steps 1-4.

a.For ovens that contain 2 magnetrons (NE1257R, NE1258R, NE1757R, NE2157R), the

temperature rise should be approximately 70oF per magnetron.

b.For ovens that contain 4 magnetrons (NE2180, NE3280), the temperature rise should be

approximately 35oF per magnetron.

* See field expedient test on the back of the page

Step 1

•Using an Ohm meter on its lowest resistance scale, measure the

resistance from one magnetron terminal to the other in either direction as

shown on the illustration on the left.

•Meter should read less than 1Ωindicating that the filament is good.

•If Filament checks good, proceed to Step 2

Step 2

•Using an Ohm meter on its highest resistance scale, measure the

resistance from one of the magnetron terminals to the metal casing of the

magnetron as shown on the illustration on the left.

•Meter should read infinity (open circuit) regardless of meter polarity.

If the meter indicates a short (Less than 1 Ω), the magnetron is defective.

Field Expedient Power Determination Tests:

•All times calculated using water starting at 70°F {21°C} brought to 212°F {100°C}.

•Times given below should serve as the benchmark. If oven cannot bring vessel to a boil within

the time given, (on High” Power) call for Service Information TOLL FREE @ 877-CMO-OVEN
