Nok Air announced on Wednesday that Flight DD9214 with 171 passengers was scheduled to depart at 3.25pm and reach Udon Thani at 4.30.
The power system malfunctioned prior to take-off, however, and the passenger cabin soon became overheated.
When repairs took longer time than expected, passengers were moved to another aircraft.
It departed at 5.50 and was in Udon Thani by 7.30.
