Question about Panasonic NN-S254BF Microwave Oven

1 Answer

Runs for 30 seconds then goes off. No heating

The microwave runs normal when the start button is pressed but goes off after 30 seconds. I tried measuring the HV at the anode of one of the HV diodes using a HV probe but the meter reading doesn't show any sign of a voltage present.

Is it 30 seconds or 22 seconds?

The 22 seconds is the giveaway.

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here.

My Panasonic microwave, Dimension4, The Genius, will not keep running after start button is pushed. It runs for only two or three seconds.


There is a thermal fuse that monitors heat from the magnetron, sometimes becomes defective, the magnetron "heats food" filiment will open on occassion, if the exhaust fan is not running microwave will shutdown.

I need to reset my Kenmore Elite dishwasher but i don't know how.


Hello,

follow the below instructions:

Unlock your Kenmore dishwasher control panel by pressing and holding the "Heated Dry" button for four seconds.

Press a series of four buttons in quick succession. Press "Heated Dry," "Normal Wash," "Heated Dry" and "Normal Wash" to instruct your Kenmore dishwasher to run a short diagnostic test

Wait for two minutes while your Kenmore dishwasher runs its diagnostic test.

Press the "Cancel/Drain" button once your dishwasher has completed its diagnostic test. This should reset your dishwasher control panel and stop the "Clean" light from blinking repeatedly.
Good luck.

Microwave does not heat.


HI, this is an inverter board issue. the magnetron would not shut down the unit. if the magnetron was the issue, it would continue to run but, it would not heat.

replace the inverter asap.

My microwave runs for 30 seconds and stops


It could be shutting off because of the heat sensor on the magnatron is over heating because of a bad capacitor or diode or the power transformer its self. This is a call for the service man BUT you know these days a microwave like this cost a couple of hundred bucks maybe a little more too. But it will possibly cost 150 or so if not more to fix the average microwave. If you really like it, then see if you can have it estimated BUT its not for the handy man to try to trouble shoot as theres extremly high voltage in these puppys even when they are not plugged in!! Good luck
