The Future Of Microwave Cooking

The future of microwave cooking is solid-state power amplifier (SSPA)

The good old magnetron does a high quality job delivering microwave energy in the microwave ovens.  However the magnetron has limitations. It solely has on-off control and the mixture of the magnetron and cooking cavity makes hot-spots and cold-spots within the meals. Use of turntable and the stirrer helps preventing hot spots and cooks meals equally. With the use of solid-state power amplifier we will get faster and more delicate cooking.

Manufacturers of solid-state power amplifiers see it as a powerful potential progress market simply because these units can substitute the magnetron’s function in the microwave ovens. So, will the SSPA-based microwave quickly replace the magnetron-based one in your house? The higher cost of the SSPA (for now) is definitely an issue. It’s seemingly that the biggest SSPA usage will come in commercial settings with their greater efficiency, lower operating cost, and longer life.

Maybe the hi-end microwave ovens will have a label on the front panel declaring “Solid State Power Amplifier Inside".

How To Troubleshoot Magnetron

How To Troubleshoot Magnetron

Magnetron is designed to generate microwaves. The physics of the magnetron is quite complicated. It is using strong external magnetic field to direct the flow of electrons in a resonant circular cavity developing tens and hundreds of watts at frequencies around 2.45 GHz. Magnetron can be tested on continuity only. The volume resistance of the terminals should be less than 1Ω. The insulation resistance between the two terminals and the housing should be infinite.

It may also be possible to detect faulty magnetron when it starts making loud humming noises. A magnetron with a short between the filament (cathode and anode) is likely to cause a loud hum when the cook cycle is initiated. Evidence of arcing (burned spots around ventilation holes in base or a burnt odor) usually indicates a bad magnetron as well. Melting or other damage to the antenna might be the result of arcing due to problems in the oven cavity or waveguide, perhaps operating microwave oven with nothing inside the oven.

Thermador Range Error Code 43

Thermador Range Error Code 43 may occur on Thermador Pro ranges if an incorrect accessory backsplash has been installed.  It may also occur if the sail switch is not positioned correctly. 

  • Possible Cause:
  1. The vents on the backsplash must be positioned directly behind the cooling fans. If the vents are not properly aligned with the fans, insufficient airflow may cause the fan to shut down and a code 43 will result.
  2. When the fan is off, the sail switch should be in the open position, and when the fan is on, the switch should be in the closed position. However, if the sail switch is mounted to the fan housing at a downward angle, and the sail is pulled further downward by the airflow of the fan, there may not be sufficient force to return the sail to its starting position (switch open) when the oven is turned off. If the switch is left in the closed position, a fault code 43 will result the next time the oven is used.All Pro ranges built prior to September 2007 (prior to FD 8709) were built with a sail switch and may be affected (see page 2 for a list of models).
  • Solution: To resolve the issue, reposition the sail switch mounting plate so that it is parallel to the bottom of the cooling fan housing. `
  1. Remove two screws which are securing the switch mounting plate to cooling fan housing.
  2. Reposition mounting plate on fan housing so that right screw hole on plate is aligned with center screw hole on right edge of fan housing.
  3. Reattach switch mounting plate to fan housing using one of the original screws. Bottom of switch mounting plate must be parallel to bottom of fan housing.
  4. Carefully drill a new hole in fan housing by using left mounting plate screw hole as a guide.
    Do not let metal shavings fall into electrical components
  5. Insert remaining screw to fully secure the switch mounting plate in the new position.
