Question "Carrier Heat Pump"
We have 2 Infinity Heat pumps, one for upstairs one downstairs. New construction units just turned on 3 weeks ago.( house not complete yet). They worked fine as we allowed them to run 24 hrs. to check them out. Turned them off. Yesterday we noticed that the thermostat (1st. floor) was not light up. Pushed on and nothing, checked breakers all ok. Decided to check 2nd. floor unit, turned on it would heat but no air coming from vents. The air handler for this one is in attic. The temp. in house was 78 so I pushed the thermo up to about 83 to try and get the blower to come on, nothing ONLY the thermo showed that the auxiliary heat was on. It was 66 out side, should the auxillary come on when it is warm out side?

I am going to call Carrier and have a Tech. come out BUT any idea what could have happened to them. They were tuned off as no need to run up electric bill in a house not yet complete. I though the thermostat would tell me problem but I don't know if it is hooked up right as it did not tell me of a problem. NO Lighting storms or power surges that we know of. How can something break just siting there. We would like to do some checking befor the HVAC man comes.

Thank you in adance :thumbup:

Carrier won't send a service tech out. Carrier didn't install them, did they?

You'll have to call the installing contractor( Your carrier dealer ).
That is who provides the first year labor warranty.

Might have sucked in a lot of construction dust/dirt.
Someone might have ran a screw or nail throught the control wiring, etc.

Just went ka-punk

Thank you "beenthere" No workers in the house since units were turned on except my daughter and I doing painting. All construction dust had been vacuumed out of vents. I did not word my first post correctly, I am having the installed come back, but did find a number on the carrier site for trouble shooting. Big mystery of how something could go ka-punk just siting doing nothing.

Free Labor

"BeenThere" I noticed that you are a HVAC Professional, Does Carrier give you free labor and parts for the first year. Should The Infinity Thermostat show why the fans (Air handler) did not come on.

Carrier doesn't provide any labor warranty(with one or 2 minor exceptions).
The installing contactor does that.

Parts warranty on Infinity should be 5 years all parts, 10 years compressor.
You shoud be able to purchase the extended parts and labor warranty. Its a good thing to do with an Infinity system.

The Infinity controller can show faults.
But the fault it shows. may not be the cause of the problem. It could be a symptom of another problem.

EG: HP switch open.

Several things can cause that switch to open. So the switch is not the cause, just the fault the controller shows.

Yes, if you push up the thermostat 5 degrees higher than the current temperature, it thinks the heatpump isn't able to keep the temp at the setpoint so it turns on the aux heat. Some smarter thermostats can avoid this to some extent (eg after a setback) but manually cranking up the temp is a good way to check if the backup strips are coming on :wink:

one problem solved

Found answer to one of the problems. The unit that was totally dead. It was the Infinity Thermostat. Thought I would post this just in case any one else has a problem with the heat pump going out. The thermostat has a fuse in it so it could be the fuse but the thermostat was the casue.
