Panasonic microwaves can be found in most Canadian homes. Being widely spread worldwide, they are intelligent and simple to use, which means you can cook fresh, healthy meals in a fraction of the time vs. a traditional oven. Our lifestyle changes over time, from shopping at fresh food markets and healthy snacks during the day to social cooking at weekends with friends & family.

Fix Appliances CA provides microwave installation services at a high level, offering the manufacturer’s warranty on the repair if you need it later. Our professional technicians prepare a guide on “how to install” the Over-the-Range Panasonic Microwave, taking as an example model NN-SE284. The concept of this installation procedure applies to all Panasonic over-the-range microwaves.

Before proceeding, it is necessary to follow specific safety precautions and requirements:


This oven must be plugged into a 15 AMP or 20 AMP, 120 volts, 60 Hz, three prongs grounded outlet. The outlet must be connected to a separate 15 AMP or 20 AMP circuit of the proper voltage and frequency.

The recommended location for this outlet is inside the cabinet directly above where the oven will be installed. This location is desirable because the power supply cord on the product is short.

The installer must perform a ground continuity check on the outlet box to ensure that it is properly grounded, and if it does not meet the electrical requirements of the product, a qualified electrician should be employed to correct any deficiencies.


For personal safety, any mounting surface for this product must be capable of supporting the product’s weight of 55 lbs (25 kg), taking into account additional oven loads of up to 22 lbs (10 kg). The total weight will be about 77 lbs (35 kg).

Proper installation of this product requires that the product be partially supported by the bottom surface of the cabinet directly above the mounting location. Therefore reinforcing this bottom might be necessary if the cabinet cannot support the weight requirement mentioned above.

Then, you must ensure you have all the necessary tools ready: adhesive tape, tape measure, screwdriver, electric or hand drill, side cutter or tin snips, metal file, electric or hand jigsaw, and marking pen. Plus, you will need specific hardware, for example, screws of different sizes and diameters, a metal brace, a flat washer, toggle bolts and others.

Over-the-Range Installation Procedure

STEP 1. Pre-installation Check Points:

  1.  Prepare space and make sure that the dimensions fit.
  2.  Confirm the separated line electric outlet.
  3.  Exhaust Preparation: it will depend on the type of ventilation required for your installation (top exhaust, recirculating, rear exhaust). If your oven is vented into the kitchen, the standard charcoal filter is already installed in your oven, ready for recirculating mode.
  4.  Exhaust Duct.

STEP 2. Using the Template

  1.  To prepare the bottom surface of the top cabinet and the wall, holes must be drilled or cut into these surfaces. A template is provided for preparing these holes.
  2.  Wall and Cabinet preparation
  3.  Fold the template along a “Rear wall” dotted line. Align the center line with the center line on the wall and the top cabinet. Tape the template underneath the top cabinet and the wall.

STEP 3: Installing the Mounting Bracket

Note: To support the oven’s weight, the bracket must be secured by at least four wood screws on the wall studs (2 screws on each side) or two wood screws on the wall studs and 4 toggle bolts through the wall.

Preparation of Bracket Assembly
Note: If Rear Exhaust is chosen, the product needs a Rear Wall Exhaust cutout opening for the Rear Wall duct, and the Exhaust adaptor must be installed on the bracket with two screws.

Installation of Bracket

  • Draw a wall stud line.
  • Centre the bracket assembly against the wall and top cabinet.
  • Drill holes.

STEP 4: Installing the Microwave Oven

  1. Remove contents from inside the oven, including the glass tray and wire rack. Be sure to close the door. Remove all contents from the upper kitchen cabinet.
  2.  Place a piece of cardboard or blanket on the cooktop, and place the oven on the cardboard or blanket. Before sliding the oven on the bracket assembly, ensure the power supply cord is accessible through the cabinet.
  3. Pass the AC cord through the kitchen cabinet hole.
  4. Lift and install the oven onto the bracket by sliding it over the bracket rails. This is easily and safely accomplished with one person on each side of the oven. Push the oven back until it is flush with the wall.
  5. Pull the power supply cord throughout, and be careful not to pinch it between the oven’s outer case and the cabinet’s bottom. The oven should fit snugly underneath the lip of the bracket’s upper edge.
  6. Insert one screw with a flat washer through the left hole drilled through the top cabinet’s bottom and into the top of the oven. Then, insert another screw with a flat washer and the metal brace through the right hole into the top of the oven.
  7. While tightening these screws, lift the front side of the oven and push it toward the wall. This ensures flush and level mounting.

STEP 5: Installing the Exhaust Adaptor and Air Filter

Note: If the Top Exhaust application is chosen, Mount Exhaust Adaptor follow steps 1-3 below. Remove 2 screws from the top plate.

  1. Mount Exhaust Adaptor.
  2. Plug the AC cord in and turn on the exhaust fan. Confirm the flapper opened freely.
  3. Insert a 31/2″×10″ adaptor with a 6″ duct onto the oven Exhaust Adaptor and secure it with duct tape.
  4. Grasp the ring of the air filter, insert the end of the air filter without the ring into the opening, and slide back into the position.

STEP 6: Operation Checklist

  • Make sure the unit has been installed according to these instructions.
  • Remove all packing materials from the oven.
  • Replace the house fuse or turn the circuit breaker back on.
  • Plug the power cord into a receptacle.
  • Read operating instructions before testing the product.
  • Turn on the exhaust fan at Turbo speed and confirm it operates using a tissue (it will stick to the filter.)
  • Confirm the outdoor exhaust flapper has opened.
  • Set the microwave oven for 1 minute and confirm the oven is operating normally using a cup of water.
  • Keep these installation instructions for the local electrical inspector’s use.

FAQ: Top Frequently Asked Questions

The average cost of over the range microwave installation costs $165 to $300 for a standard replacement in our region. We offer installation with a warranty of labour for $199
A blown main fuse is the most common cause of a microwave oven not working. The main microwave fuse will cut the flow of electricity if too much current passes through it.
If the microwave overheats, the thermal fuse cuts off power to Panasonic Microwave. To determine if the fuse has blown, use a multimeter to test it for continuity. If the thermal fuse does not have continuity, it must be replaced with the original part number.
Be aware that there is always a reason why a fuse blows. Most Panasonic microwave oven models use 20A/120V ceramic fuses.
