Hello,
A few weeks ago, during a cold snap, our heater stopped working. I tried the thermostat on A/C as well, and it was not working either. After some research and troubleshooting, I finally realized that the inside unit has it's own breaker in the attic - near the inside unit. I flipped the breaker on and off, and it started working again.
Since then, the inside unit has stopped working 3 or 4 times, and I have had to throw the breaker each time, thus making the unit work again. Today, it stopped working again, however when I throw the breaker today, nothing happens...
We have a American Standard split unit, Electric. Outside unit is American Standard Allegiance 14 (model# 2a7a4030b1000aa). Inside unit is American Standard Trane (model# TWE031E13FB1). Thermostat is a Ritetemp (model# 8050 0 84615 00020 4). There are a total of 4 breakers for the system: 2 at main breaker box - labeled 'Heat' and 'A/C'. 1 at the outside Unit, and 1 in the attic at the inside unit.
I am a true novice, so I am really not sure where else to look. Any thoughts or advice to troubleshoot the system? It's now cold again here, and my fiance and pets are shivering all night and day.. Please help!
Thanks,
Michael
Ok this can be simple or tricky is the breaker that trips the same size as the one in the breaker panel 2.look in the unit itsself see if there r breakers inside the unit there usually are and they might have tripped it might be as simple as flipping a breaker but the problem with the breaker tripping is what concerns me now it may just be undersized or getting weak and finally crapped out get ur meter and flip the breaker on and see if u r getting power to the unit if ur not u have gott a breaker that isnt letting power go thru now if u have power u might have a bad blower motor turn the unit on and calling for the fan on if the fan doesnt start try spinning the blower by hand now if it starts then u probably have a bad capacitor they r usually mounted on the side of the blower housing it is oval and its gonna be a 5mfd(microfarad) or 7.5mfd and that couldve been what was kicking the breaker now if the blower is stuck and it wont turn or its very hard to turn then make sure the blower wheel hasnt slipped on the shaft and is rubbing up against the housing if it is just loosen the set screw and set it back even and tighten it back up now if the wheel is free and its still hard to turn then u have a bad blower motor its not a big deal to change out and not real expensive if this dont help hit me back and well walk thru it hope this gets lil momma and the pets warm have a good day
ok now check ur breaker again go with ur black lead to a good ground and ur red lead on one of the terminals u should have 120 around about on both legs now test the output side u should have the sameif u dont u have a bad breaker now another way to find out is take ur red lead and put it on one input and take ur black lead and put it on the same side output u should read nothing do this on the other side the same way if u get voltage on either side that means ur breaker isnt letting power go thru and ull have to replace breaker now u have to do this with the breaker on so be careful

Okay, I opened up the breaker and tested the input side: tested on Vac 600 @ 245, and tested on Vac 200 @ 122. The output did not read anything on Vac 600, but it did read @ 122 on Vac 200. Does this mean that I have a problem with the breaker?
Inside the unit, there is a small fuse (looks like an auto fuse, and this is still intact). I have not gone any further yet.
Okay, all 4 terminals (input & output) showed 122. When I tested the other way - one-side showed 0, but the other-side shows voltage. So.. I have a bad breaker?

Problem solved! I went to Home Depot and purchased a replacement breaker. Installed it. And now we're up and running! I really really REALLY appreciate your help!!! Everyone will be warm and happy in no time. Thanks again!
