High Electric Bill and Microwave Oven with Hood Exhaust Fan

This electrical wiring question involves a High Electric Bill and a Microwave Hood Exhaust Fan in the Kitchen of my House.

Microwave Oven with Hood Exhaust
If the microwave oven is not operating then it should not be consuming electric power, therefore I do not think that this would be the cause of a high electric bill.

You may consider having a technician evaluate the cause or problem with the microwave oven. I have repaired microwave ovens where a fuse was blown due to over usage or when attempting to heat food and a metal object or container caused the fuse to blow.

If the hood fan is operational it may be best to keep the unit in place and use the exhaust fan, otherwise once the unit is removed you will need to replace the unit, and in some cases the vent pipe will need to be reconnected to provide ventilation when cooking.

Another option is to replace the non-working microwave oven with a conventional hood exhaust fan and continue using the countertop microwave oven, as you have described.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
