Stackablw dryer not heating up/

Hi,

I have a stackable washer/dryer, whirlpool and serial # MK5131921in my condo unit. My tenant called me up and said that it’s not heating up, Does anyone know what that could be from? and How much? Thank you

If your heating element is good, it’s probably item 15 or 5 on the diagram (thermostat or fuse). A cheap $2 ohm meter will tell you which one.

I would check the power first.
Try flipping the breaker off/on slowly a couple times, sometimes you can loose half the line without actually tripping the breaker.
If this does nothing, check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Be careful as 240 volts is lethal !!!

If you are unfamiliar with electricity then get a pro in to check/fix the unit.
