Customer Question
I have a Miller...

I have a Miller P3rA 024k central air, and a Miller cmf2 80 PG propane furnace. When I put on my A/C it doesn't blow on the inside, even though both the fans on the unit outside are blowing, and I can't find any leaks in the ductwork under the house.

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

Yes, and I replaced the batteries on the thermostat. I hosed off the filtyers on the ac unit outside, and tried to get the frost off the inside.

Contractor's Assistant: Do you plan on doing the work yourself?

If I can I will, it depends on what the problem is.

Contractor's Assistant: Anything else we should know to help you best?

The fan on the unit outside seems okay, but it seems to not get past where it meets the furnace. Is there a problem with the fan on the furnace?

Hello, so far the phone call offer box has not come up on this end, it should in a few minutes,

.

so far it sounds like the compressor is not running

Take close up, exceedingly well focused photo's of the wiring diagram glued inside the furnace/air handler door, and the printed circuit board mounted on the blower , that shows where the thermostat wires connect, and the wiring diagram glued inside the electrical controls box mounted INSIDE the unit that sits on a slab outside the house.. and I will mark that up with trouble shooting instructions.

Use the 'add files' link next to your send button to get the photo(s) tome.

http://ww2.justanswer.com/help/how-do-i-send-photo-or-file-expert-hl

We can go from there with training, coaching and diagnosis.... without a time limit, In depth with as much detail as needed .

.

When we finally get the situation solved, please select the 'finish and rate your expert link' near the top of your page and click on it.

.If any of this is beyond your skill sets, or fails, tell me which directionyou are from the center of the nearest town or city and I will locate a well rated service outfit in your area andrun them through my own screening process for you.

.

Or I can coach you to a diagnosis if you have some technical skill sets.

Your question in that case goes beyond 'Just a simple Answer' and will require a few hours training and coaching to a full diagnosis and possible repair … IF you have a multi meter and considerable mechanical skills, rate this answer so far positively and I can do all that for you without any time limits … even if it takes days.

-----------------

That way I do not loose my shirt helping you, you can still refund if I fail.

$25phone calls are 100% optional but will speed up the training,coaching and troubleshooting process in most cases.

Is there a dedicated fan in the furnace especially for the A/C?
HVAC Technician: Phil, Mechanical Engineer replied 2 months ago

There is just one main blower, two speeds, low speed for heat, high speed for cooling and that is controlled by a relay soldered into the printed circuit board

when I put on the (outside air) fan switch in the furnace it doesn't blow cold air, so I didn't know if it came from underneath or from above.
HVAC Technician: Phil, Mechanical Engineer replied 2 months ago

It only blows cold if the AC unit located outside is running,
