We just replaced the power cord and outlet for a Kenmore Elite HE3 dryer and now it will not go on. I flipped the circuit breaker on and it said PF and now I get nothing.

This means 'Power 'Failure'.
This could be from the circuit breaker being tripped and then was reset, wall outlet issue, or possibly if the cord was replaced then the screws conecting the wires to dryer may not be tight. Make sure dryer in unplugged before checking connections.
Some homes have an energy management system where higher energy use appliances are given a priorty so they all cannot run at same time so keeps your electric bill lower.
For example, the water heater and a/c system would be wired to override the dryer so if both these were runnng and then you turned on the dryer, the control unit would shut power down to dryer within a short time.
Hope this helps.

Press and hold the "Start" button to restart the dryer cycle if the "PF" (power failure) error code appears. This code often appears when a cycle is interrupted before it completes. You may also check the breaker or household fuse, and ensure the machine has not come unplugged.

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

this is regeristering a power failure,you will need to check the main power supply.there is also a chance that the main control board may be faulty you will need to check all the wiring to the unit.

Sorry to read about your problem, I hope this helps you out.

their is no reset button on this unit, you can try hitting pause/cancel button twice, this will stop any action, and you can flip the circuit breakers to the unit.

A dryer not heating usually means that either the heating element is burned/broken (open circuit); a thermal fuse in line with the heating element is blown or; a thermostat is faulty.

Dryer needs to be partially disassembled to diagnose with a multimeter.

HI, there may have been a slight power failure within the home breaker unit or the dryer may have lost power to the control for some sort of reason.

I recommend a thorough inspection of the terminal block on the back side of this unit. make sure the power cord is attached tightly and the wall outlet is secure and holding the power cord correctly. if everything looks great with the terminal block and the power cord is plugged in the outlet correctly, simply unplug this unit for 5 minutes to reset the control. after the 5 minutes are up, plug the unit in once more and the PF alert should reset.

Make sure the breaker box in your home is working properly. (the actual breaker switch for the dryer must be in the on position)

The manual says that two circuit breakers used,and that the dryer
can spin but no heat if one of them tripped, check your panel and see
if any breakers are tripped. If this was the problem,have an electrician
check the circuit.

check block where power cord attaches.
