Hi I need a hand . The Set works great during the summer and warm so I went ahead and replaced caps that people recommended. Now I have an diognostic code 21 X-ray protection What is that and how do I go about troubleshooting it. Thanks Chris}
You've got to get a meter on the B+ line. If it's going over 135v the B+ regulator package could be bad. The part # starts with STR (STRD1005T, STRM6511, STRS6301 etc..)
Thank you very much for the advice Gonna do that today. I was about to take out the jigsaw but ill try this first. Im not near the unit now where do I find this point to check On the regulators thanks Chris
