DANGER
DANGER
Electrocution can cause death or serious injury. Burns from hot
or cold surfaces can cause serious injury. Take precautions when
servicing this unit.
• Disconnect the power source.
• Do not stand in standing water when working around
electrical appliances.
• Make sure the surfaces you touch are not hot or frozen.
• Do not touch a bare circuit board unless you are
wearing an anti-static wriststrap that is grounded to an
electrical ground or grounded water pipe.
• Handle circuit boards carefully and avoid touching
components.
To measure the start winding resistance, measure across the C and S
pins.
To measure the run winding resistance, measure across the C and R
pins.
Also check S to R and you should get the sum of the run and start
windings.
To ensure the windings are not shorted, check the S and R to ground
