I have a trane unit that has no power going in from the shut off box on the side of the unit but power is coming into the box ! Can time delay cause this problem

Shouldn't if they are good. All they to is to momentarily shunt power during a startup of a motor or compressor. Run a continuity text to make sure they are good. Should have 0 resistance if good and infinity if bad.
