i replaced my stove and now the microwave won’t turn on at all, no lights, no display, nothing. did i break it?

Diagnosis

You have not "broken" the microwave in the sense of a component failure; rather, you have likely interrupted the electrical circuit. The GE Profile PVM9005SJSS is powered by a standard 120V three-prong plug that resides in a dedicated junction box or outlet located inside the upper cabinet directly above the unit. During a stove replacement, it is common for installers to bump the cabinet or for the vibration of moving heavy appliances to loosen a plug that was already marginally seated. Furthermore, because you replaced the stove, there is a high probability that a circuit breaker tripped during the installation process. If the new stove drew a momentary surge of power or if a wire was momentarily shorted during the swap, the breaker serving the microwave circuit (which is often on a separate leg but in the same panel) may have flipped. You can confirm this by checking if the display is completely dead (no clock, no backlight) and verifying if other outlets in the kitchen are functioning.

How to Fix It

To restore power to your PVM9005SJSS, follow these precise steps to ensure the connection is secure and the power source is active:

1. Safety First: Ensure your hands are dry and you are not standing in water.
2. Access the Plug: Open the cabinet door directly above the microwave. Reach inside and locate the power cord. Since this model is an over-the-range unit, the cord is often tucked tightly against the back wall.
3. Reseat the Connection: Firmly grasp the plug and push it deeply into the outlet. If the plug feels loose, it may have been partially backed out during the stove installation. Ensure it is flush against the wall plate.
4. Reset the Breaker: Go to your home's main electrical panel. Look for the breaker labeled "Microwave" or "Kitchen." Even if it doesn't look tripped, flip the switch completely to the "OFF" position and then firmly back to "ON."
5. Check for GFCI: If your microwave is plugged into a GFCI outlet (one with a "Reset" button), press the "Reset" button firmly until it clicks.
6. Power Cycle: Once the plug is secure and the breaker is reset, check the microwave display. If the clock is flashing, the unit has power and simply needs to be reset.

If That Didn't Work

• Inspect for Cord Pinching: Gently pull the microwave forward about 2-3 inches from the wall (you will need a second person to hold the unit to prevent it from tipping). Inspect the black power cord for any visible kinks, flat spots, or exposed copper. If the cord was pinched between the unit and the wall during the stove swap, the internal wiring may be severed, requiring a cord replacement.
• Test the Outlet with a Multimeter: Use a digital multimeter set to AC voltage. Insert the probes into the outlet above the microwave. If you do not read approximately 120V, the issue is with your home's wiring or a failed breaker, not the microwave itself.
• Verify the Thermal Fuse: If the microwave experienced a massive power surge when the new stove was plugged in, the internal thermal fuse may have blown. This requires removing the outer chassis to test for continuity across the fuse using a multimeter. If the fuse is open (no continuity), it must be replaced.
• Check for a Blown Internal Main Fuse: Locate the main ceramic fuse on the internal power entry module. If the filament is broken, the unit will be completely dead. Replace it with a fuse of the exact same amperage rating to avoid frying the control board.

Heads Up

• Dedicated Circuit: The PVM9005SJSS requires a dedicated 120V circuit. Never use an extension cord or a power strip to connect this unit, as it can lead to overheating and fire hazards.
• Capacitor Warning: If you decide to open the chassis to check fuses, be extremely careful. The high-voltage capacitor can hold a lethal electrical charge even after the unit is unplugged for several hours.
• Alignment Check: When pushing the unit back against the wall, ensure the power cord is routed through the designated cutout to prevent it from being crushed against the drywall.
• Voltage Stability: If your new stove is an induction or high-power electric model, ensure your kitchen panel can handle the simultaneous load of the stove and microwave to prevent future breaker trips.
