A Frigidaire washing machine that makes a humming noise but does not begin the wash cycle is usually receiving power, but something is preventing the motor or another component from operating correctly. The sound may come from a pump trying to run, a motor that cannot turn, or an object blocking a moving part.
Ignoring the problem can make the repair more complicated. A motor that repeatedly attempts to start, for example, may overheat if the underlying obstruction or electrical fault is not corrected.
