Protect can't work without 10k NTC (thermal protect), but you can use 10k resistor instead NTC for test.

thanks sir for the reply.
ok i will buy 10k ntc and check.

hi apex sir,
now i put 10k ntc .
now the protect circuit is working, but when power on , the relay delay time is one second ,because the led indicator only blinking once and after relay connects the led permanently lights on, how can i increase the delay time to 3 or 5 seconds?
