We use the STW0925H! in 60 rooms on this property and have encountered similar problems that were caused by weldedd contacts on one of two relays that controls the electric strip heat. They can be replaced if needed.




PTHP's and PTACs employ thermal fuses as well as a bimetal limit stat on the heating element to limit risk if fan motor were to fail and the heating element were to remain energized. It would be wise to check that both are fuctioning properly while you are servicing the unit.

Hi,
It could be the relay or the strip heat....
To figure out what is wrong you will need to check if power is getting to the strip heat or not...should have 220-240 V across the two legs going to the heat strip...when the heat should be on.
