Frequently asked questions
I just installed the dryer and see PS. What happened?
The power cord was likely wired to the wrong terminals. Recheck it against the manual diagram.
Can a loose screw really cause this?
Yes. A loose terminal creates resistance and voltage drop, which the dryer reads as incorrect wiring.
Is it safe to rewire the cord myself?
If you are comfortable and the breaker is off, yes. If anything looks burnt or confusing, call an electrician.
