Hello everyone and greetings. I have got my hands on this massage chair that has all it's functions working all right except for the up down mechanism. As soon as it is started the main assembly moves up and hits the upper limit switch but the drive motor does not stop and starts to vibrating and get hot. I pulled out the control circuit and after some testing found one of the two triacs to be leaking. M1 and M2 and Gate all have a small voltage drops when measured with a multimeter.
The triac in question is a BTA06-600C. I have BTA06-700B's which I guess should work fine with the circuit. I don't have too much of a grasp on triacs and was wondering wether they have compatible issues, like when using transistor in pair.
Should I replace both the triacs with the ones I have?
N.B. the triacs are driven by two MOC 3063 IC
Thanks for the feedback and have a great day. Cheers
