Unit has completely quit. I've read all the other subjects trying to find an answer, So I think I have it narrowed down to a few things.
1st, I have no power to the blend air 2 system From the transformer. bad transformer ? Will it kill the whole system?
No Voltage output from the red wire on the LOAD side.
Not sure how to completely check the transformer.

I have 240 coming out of the Breakers on the unit.
Also 240 at the bronze terminals on top of the Sequencer
No voltage @ silver terminals on bases of Sequencer

Not sure what to check on the black fan relay need some help on this

I'm testing with the unit in cool/auto with the T-stat turned way down.

I took the day off from work and will stay at the computer this morning. If you could let me know what to check I'll do it right away.
Thanks ahead of time for any help you can give me.

Well I just took the blend air control off and looks like some condensation has driped down in it.
I can't tell if it 's hurt becase I don't seem to have any power to it.

Okay, It was a bad transformer. System is working.
The only question now is when I turned on the breaker my Blend air panel has a buzzer going off every 5 seconds.
The switches were positioned right one down and left one up.
Put both down and it stopped.
The yellow light is on. What is the buzzer, and what way SHOULD the swithes be?
Thanks again, Don
