The small springs found inside microwaves play critical roles in determining their overall performance. They might not be easily visible due to their size but are vital for the device to function properly. This article will explore the use and placement of these springs in a microwave and provide specifications for best performance. It might seem surprising that such small parts are important in a microwave. However, the initial design of microwaves included springs as an integral part; hence, their use is standard in these appliances. We will also provide a guide on how to replace these springs safely, a skill that can improve the longevity and effectiveness of your microwave.
Where are the Springs in Microwaves?
-
Door Latch: Springs are positioned inside the door latch mechanism of a microwave. They contribute to the closure of the door during usage, and facilitate opening with ease when needed. The design of this mechanism requires careful spring selection. If a spring does not have adequate strength, it may not maintain door closure, which could result in microwave radiation escape. Conversely, extremely strong springs can make opening the door difficult.
-
Button Panels: Springs are also located in button panels. They are responsible for returning depressed buttons to their initial position, making them available for subsequent usage. The kind of spring chosen has an impact on the user interaction. For instance, a spring with a lower spring constant will provide a milder push, but may wear out faster under high usage. Therefore, a balance between the tactile response and the lifespan of the spring is necessary in the designs of engineers.
-
Turntable: Some microwaves utilize springs in the turntable mechanism, where they keep the drive belt taut to enable the rotation of the turntable. The selected spring for this component should provide adequate tension for rotation and should not place unnecessary stress on the belt.
Requirements for Microwave Springs
Microwave springs experience tension and release cycles during their use. This is manifested in the constant opening and closing of the microwave door. As such, springs with adequate fatigue resistance are required to prevent failure.
Given the high temperatures within microwaves, one may assume that the springs must be able to withstand these conditions. Keep in mind, these springs will not be placed within the heating chamber, for reasons I hope are obvious. Heat can still penetrate the walls of the microwave, however this amount should not be significant enough to be of concern of any standard spring material.
In designing microwave springs, corrosion resistance must be accounted for. Regular use of the microwave exposes the springs to food debris and moisture, which can cause corrosion. One potential material is chrome silicon, recognized for its resistance to corrosion. However, the use of this material may lead to higher costs and may not be appropriate for all designs. Therefore, the selection of material involves evaluating between cost, performance, and the planned lifespan of the microwave.
Springs in the door latch mechanism illustrate the need for safety in spring design. These springs must operate reliably under continuous high temperatures or sudden hard impacts to keep the microwave from functioning with an open door, which could potentially cause harmful radiation leaks.
How to Replace Microwave Springs
Before you begin, it's crucial to disconnect the microwave from its power source to avoid electrical shock. With a screwdriver, the cover or panel of the microwave can be removed, a necessary step in nearly all microwave spring replacements. For instance, to replace a door spring, the door needs to be unhinged to reach the latch mechanism housing the spring.
During removal, observe the spring's initial position. The new spring must be installed in the same configuration to maintain proper functionality. Incorrect placement may impair the microwave door function.
The button spring's replacement also needs a similar approach. Begin by removing the panel housing the buttons, then locate and substitute the spring for the malfunctioning button. Its correct fitting is crucial as it influences the reaction of the button after being pressed.
The replacement of a turntable spring might need additional steps, possibly involving the detachment of the turntable motor assembly. In cases involving detailed disassembly, consult your microwave's manual for instructions specific to your model. This helps in understanding the assembly and hence the accurate placement of the turntable spring, hence improving the replacement process outcome.
