Longer heating times may indicate a magnetron tube that is old.

Microwave ovens beam their energy in the form of an inverted cone thus most of the energy falls in a circle outside of the center.

Move your article to be heated to the outside of the oven and use more of whats left of the dwindling heating source.

How do i adjust power level


There are no heat levels on a microwave oven, only power levels. I am not aware of any method of checking the power level except to boil water. Boil water at each level and time how long it takes to boil. The lower the power, the longer it should take. If there are no differences in the time, the oven is not functioning as expexted.

Silvercrest microwave, table dont turn no heating


follow the steps, use the VOM for fix it. God bless you

  1. Check the power diodeThis electronic component is responsible for transmitting current in one direction. If the diode becomes defective it will cause your microwave to not heat. Test the diode and replace it if necessary.
  2. High voltage capacitorResponsible for storing electricity, this part is a key component in any microwave. Remove, discharge, and test the capacitor to determine if it requires replacement.
  3. Damaged magnetronResponsible for generating waves and producing heat. When your microwave is no longer heating properly, replacement will be required.
  4. Thermal CutoffsExamine the thermal cutoffs on both the magnetron and the oven itself. Take off one of the leads and using a volt-ohm meter on RX1, check the terminals. If you get a result other than zero, replace the thermal cutoffs.

Mic.oven takes longer to heat food


The microwave may not be cooking at full power, check the settings. If okay the magnetron is on it's way out and will eventually fail.

Power on, everything sounds & looks normal but not heating food. When I hit power level option it does not say high, medium or low any longer.

Coffee is not hot.


Possible that the selected time or power was insuffcient. Use a longer time with the same power rating to steam the coffee.
However if the coffee is not heating I am afraid we need to check on the Magnetron, capacitors or transfomer.Can it be also low mains voltage?

Microwave taking much longer to heat food


The microwaves are produced by what is known as a KLYSTRON TUBE. Like anything, early failure is possible. There is also the possibility that the transformer or electronic circuit providing the correct voltage to the KLYSTRON has failed, either from over-use, manufacturing defect, or leakage from the KLYSTRON enclosure, which creates heat.
With microwaves being as CHEAP as they are, replacement should not be an issue.

Kenmore microwave Model 72 8975590 (750 W) is taking longer to heat food. Takes 3.5 min to bring one cup water to boil, previously took 2,5 to 3 min. Does the element lose power over time?


I can adjust the power level so that circuitry seems to be ok. The longer water boil time could be partially due to the colder winter temperature of the inlet water. We'll just cook the food a bit longer as long as the magnetron is still working.

Microwave now taking longer to heat same cup of water - safe?


Actually if there is a larger than normal power demand in your area from a cold spell and the input line voltage drops even 5 volts from 120V to 115V it can make a huge difference in the performance of your microwave. It can also be signs of a weak high voltage capacitor or a failing high voltage diode. Neither of those are an excess espense repair.
If it is working normally but taking up to 30 seconds longer to get the results you had in the past check the input power first. I would also check the fuse holder inside the chasis to see if it had weak contacts and not grasping the fuse very well. If it looks like it has been hot or the fuse is a solder type and you see signs of melted solder there is a problem with either the fuse or fuse holder (this can act like a resistor and drop the input power voltage.)

Microwave is not heating anything


Hello Nicoleewilli,
If your microwave is a tabletop model and it no longer heats up food in the oven compartment then there is a high probability that one of the main components that generates microwave energy has failed. ( Magnetron tube, filament transformer, HV Capacitor but none are user servicable unless you are properly trained. Unfortunately, the cost to repair would probably exceed the cost to replace so unless there is some obvious problem ( external fuse or power cord issue).. it probably isn't worth fixing..
Sorry to be the bearer.. but. that's my take..
Good Luck
Rick

Microwave won't heat anything


take the cover off the machine and look for a 13amp fuse that supplys the tranformers. BEWARE!!!
when you open the machine disconnect from the mains and do not touch the high power circuits the capacitors can hold a charge that can kill.
