My outside compressor and fan won't start. On the contractor relay, I get a reading of 120 volts on each leg going to the contractor but when I measure the voltage across the two 120 volt legs, I get 0 volts. It should read 240 volts.
Any ideas as to why I get 120 volts on each leg but together get 0 volts?
Thanks in advance for any help.

Sounds like you might be getting bleedover when checking one side at a time
The correct way is to check both sides at the same time
Sounds like you might have a blown fuse on one link or breaker that's half kicked,check fuses or turn off breaker and back on check again power with multimeter

Thank you for the advice. I'll check it out and let you know.
