Kitchen FAQs
Microwave Repair FAQs
My microwave is sparking inside. Is it dangerous?
Sparking is often caused by a burnt waveguide cover or food residue. Stop using it immediately as it can lead to magnetron damage. We can replace the cover safely.
It runs, but the food isn't getting hot. What's wrong?
This usually indicates a failed magnetron, a capacitor, or a diode. These are high-voltage components that we can test and replace.
The turntable isn't spinning. Can you fix it?
Yes, this is typically a broken coupler or a failed turntable motor. We can replace these parts to restore even heating.
My microwave's display is blank or non-responsive.
This could be a blown main fuse, a faulty touchpanel, or a failed control board. We'll diagnose the power issue on-site.
Why does my microwave makes a loud humming noise?
Loud humming often points to a failing magnetron or high-voltage transformer. It should be inspected by a professional immediately.
Do you install over-the-range (OTR) microwaves?
Yes! We provide professional mounting and electrical hookup for OTR microwaves, ensuring they are secure and properly vented.
The door latch is stuck or won't click shut.
Correct. The door must latch for the safety switches to engage. We can replace broken latch springs or the entire door hook assembly.
Are countertop microwaves worth repairing?
For small, cheap countertop units, it's often better to replace them. However, for premium or built-in models, a repair is usually much more cost-effective.
What brands do you service?
We service all major brands including Samsung, LG, GE, Whirlpool, KitchenAid, and Panasonic.
What is your diagnostic fee for microwave repair?
Our diagnostic fee is $69. This fee is completely waived if you proceed with our recommended repair.
