Check that you have the proper power at the plug.
L1 to Neutral and L2 to Neutral should be 120 volts
Also L1 to L2 should be 240 volts.
It is not uncommon to loose half the line without actually tripping the breaker.
Depending on which side drops out the unit will run but not heat.
Flip the breaker off/on slowly a couple times.
Be careful, 240 volts is lethal.
thank u for your response,there is no problem with power ,L1 and L2 already giving me 240

Is the heater itself OK?
Looks like the heater relay and the motor relay are the same.
Check this just to be sure.
If they are the same, swap them
Now if it will not start you know the relay is shot.
yes i am thinking aswell this could be the heater relay but not a control board which is beside the relay? thank you for your quick response
Could be the control board but you want to eliminate everything else before coming to that conclusion as it is the most expensive part.
