Receptacle tester shows hot & ground reversed. No wiring changes have
been made since home new 25 years ago. Plugged in iron and power went
out but didn't flip breaker. All outlets in room also out. Later all
worked, plugged in iron and all went out, and breaker still not
flipped. Iron works fine elsewhere. Replaced breaker and outlet.
Still nothing. Outlet tester shows hot & ground reversed for all
outlets on circuit. Pigtail tester shows neutral and hot both hot for
all outlets on circuit. There is also a light switch and ceiling fan
on circuit. Suggestions appreciated. Thanks.

You have an open neutral (white) somewhere in that circuit.
Those plug in testers will not give correct results with an open neutral
especially when stuff is still plugged into the circuit.
The 'pigtail' tester also fools you because with the neutral broken you get
a hot reading as the voltage makes a circuit from the hot wire through
different loads -such as light bulbs- into the 'floating' neutral wires. If
you unplugged everything and turned off all lights on the circuit you would
probably get accurate indications on the testers.
