I had an electrician working on some electrical issues I had with a few outlets in my house. shortly after he left, I noticed my Kenmore electric range was displaying "PF" on the LED display.

In general house hold circuit breaker of the house is 15 Amps or 20 Amps.

Either you have defected (weak) circuit breaker and wiring or bad Microwave oven.

The 99.99 % house hold Microwave ovens pull less than 15 Amps. They may have internal ceramic 15A fuse or 15 Amp internal circuit breaker.

To isolate your problem:

1. Plug your Microwave oven to different areas (different electrical circuit) if the different circuit breaker still trips... your Microwave oven has a short - Most of them has a small ceramic fuse 15 amps fuse.-also check some inter lock switches at door .

2. If the Microwave oven works Ok then you may have:

2a. You may overload the existing electrical circuit, try to unplug some other appliances

2b. You may have bad electrical outlet receptacle (Replace it with the same type , - may need helps from licensed electrician)

2c. Weak or defect house hold circuit breaker. (Replace it with the same type , brand - may need helps from licensed electrician)

Depends ... what is 'normal house voltage' where you live?

If you are installing a new electric dryer in the USA, typically, they operate at 220 Volts. If there is no special outlet at the place where you want to use the dryer, you will have to have an electrician install the proper gage wire and outlet for you. Expect to pay up to $200.00 or more for this installation from the house main panel to the dryer location.

If there is a gas line at the location, you may want to consider exchanging your electric for a gas model.

From what you mention, my take on the issue is that a Fuse or board will either work or not work.My guess is a loose connection or damaged cord somewhere. Assuming you are not electrician , what I would suggest is just to check the cord from the wall outlet to dryer and look for any bends, or damage to the cable, WARNING do not touch it while still connected to outlet if there is any sign of damage. Also use a hair dryer as an example , and just plug it into the outlet to check if the electricity outlet itself, has not perhaps failed.Failing this, a loose earth connection, or wire to unit might have failed and best bet here is to have an appliance person check it over, good luck

Obviously, it's an electrical problem. Electrical problems are many, yet they elude us when determing the CAUSE. You describe an INTERMITTENT OVERLOAD on the circuit... the challenge here is to determine WHICH circuit!

If you're not an electrician, then let an ELECTRICIAN troubleshoot it.

I, as an ELECTRICIAN, could teach you what you need to know to troubleshoot/diagnose electrical issues like this. However, this is not the forum for it. Have an electrician diagnose it. BEST ADVICE I CAN GIVE.

You reversed the black and white wires on what? Don't ever do that. One is the line and one is common. They are polarized for a reason.
Immediately stop using that outlet before you burn your house down. Switch the breaker off to that power circuit, then have a qualified electrician check it out.

Get a repairman in to check for a damaged drive train on the washer and an electrician in to check the wiring in your house

Switching a high power electric shower on can cause some voltage drop which in turn causes the lights to dim for a short period.

But having a washer stalling on wash doing it sounds as if you have some major issues with the house wiring.

I would have an electrician check to see if you have a grounding issue. Especially at the outlet that you have the power strip supply plugged in, Check to see what kind of your circuit panel is going to trip for electrical arc or electrical short. Newer panels should have both. Older just for electrical short. Have your electrician make sure your wiring is entirely copper, if it isn't and it's aluminum. Have him make sure the outlets are aluminum rated, and not designed for copper. Defintely check grounding. Good Luck
