Having problems with your Air Conditioners ?

I installed the rth2310 and it seemed pretty straightforward. I had R, W, Y, G, on the old thermostat, and hooked them up to the same, with R to Rh with the jumper in place. Now, the snowflake cooling symbol is on all the time, and when I turn on the heat, it just runs all the time. This is a zoned system. I replaced another thermostat at the same time, and it works fine (it had a black wire going to Y, but otherwise the same).


Answers :

You need a jumper between RC and RH.

I have a Carrier Standard Programmable Thermostat dual zone system heating / ac. I just moved in a month ago, and have inherited this system. At least once a day I find the 'time' display flashing on at least 1 of the 2 thermostats, as if power was lost. I can't find anywhere in the manual as to why this happens. Is it really because of lost power? If so, why is this happening?

Re Carrier Comfort Zone II system with 4 zones. We are in an area with occasional momemtary power outages. When such an outage occurs the thermostat defaults to the LOWEST temperature setting and proceeds to freeze the whole place and run up our electrical bill - thousands over time - as we often travel, and the thing runs constantly. Carrier says unequivocally in owners manual that settings will not be lost however this is not the case! I'm suspicious that a backup system for the thermosta

My central ac system occasionally runs too long and the temperature gets way too cold. The digital thermostat reads that the temperature is too high so the ac still runs. This doesn't happen all the time but last night we had the thermostat set on 74 and when my wife got up during the night it was 67 degrees in the house (another thermometer read 67, the thermostat read 78)


I have seen this is many digital thermostats. The worst problems usually come from the touchscreen thermostats. I would suggest installing a new thermostat. Make sure that you read the instructions before you even remove the old one. ... Air Conditioners

I recently bought a 4 ton 14.5 SEER Rudd Spilt system using R-410 and matching Rudd furnace. This system replaced a Lennox 10 SEER 4 ton unit.

I have Carrier Comfort Zone 2 on a York system. Everything has worked fine. After recent lightning strike, the controller is not responding correctly. It flashes E1 alternating with the current temp. No matter what the programming, it seems to start cooling when the house gets to 84-85 degrees inside and then stays on continually until it hits the programmed 76-77. How do I test to see if zone panel or thermostats need replacing?

I have a york hvac system that is 5 years old. I have the thermostat set at 74 and when it turns on only the fan runs circulating the existing air in the house about 20 percent of the time. The ac works great when it is running but i'm wondering why it doesn't always come on. Just replaced the thermostat thinking that was the problem but it did not help. Sometimes after the fan runs for a half hour or so the ac will finally kick in and start blowing cold air. The lines are not frozen at a

Have Coleman-Evcon heat pump system. Model DRHS0421CB. Condensing unit has intermittent no run condition. I replaced the contactor, as it was a few years old. I eliminated the thermostat from the equation by twisting together the RYO wires at the thermostat sub panel. This makes the air handler run and MOST of the time also makes the condensing unit come on as well. When it does run together, it cools great. Suction and discharge pressures are normal. The float switch is ok and no water prese

I have a Dometic rooftop AC, 59516.331, and an Atwood 8531 furnace with an analog Duotherm thermostat. I have recently replaced the thermostat. My heat system will only run with the thermostat maxed out. When the system reaches temp., I get a constant clicking sound (I think in AC unit area), whereas the system starts and stops constantly.

My goodman heat pump has frozen up 3-4 times already this summer. It is a dual system 10 seer (i believe are the terms). Every time someone comes out they can't figure it out because the system is running fine by the time that they come. Two years ago the blower or activator was replaced (maybe the replacement part isn't so good?) The unit is 9 years old. Last year a guy charged it and about a month ago when it was checked the freon was only a little low. I'm SO tired of this issue. Any ideas

Penguin a/c The original Penguin A/C on my 1999 Airstream failed in August 2006, and the roof portion was replaced by an Airstream dealer. The replacement would not work with the existing thermostat, which was replaced by a thermostat designed to handle multiple zones, although I have only one zone. The combination operated irratically; it was often necessary to set the demand to 50 degrees to get the unit to start on a hot day. Once the unit was cool, any adjustment to a moderate temperature (

Tech said that the Carrier equipment controller module board is bad. The house would heat when the digital thermostat did not call for heat in multiple zones. Quote was about $1500 to replace the board, replace the multiple zone thermostat with three thermostats in each area, and fix one duct. Sound about right?

I have a Bryant split system AC that is 18 years old. We have been away all summer (2 1/2 months), during which time the thermostat was set to 80°F. We live in SE Virginia and summer temps are 80's or 90's. We arrived home less than a week ago and turned the thermostat down to 72°F (at all times - we have small children and I am pregnant, so we need the house to be cool 24/7). The system was working fine until this afternoon, when I noticed the house was warming up. The temp had reached 76°

19 seer infiniti system, system will run for 2 mins. and then cut off and it will not show a code to the outside unit board or the thermostat. Replaced the thermostat and the outside low voltage wiring, then went to test mode on thermostat. Turned high cooling for 15 mins, it will run for 10 mins and then cuts off. It still does not show a code. If you go to the thermostat and turn it off, and reset it to cooling it will run for 2 mins and will cut off.


This cut off is very likely being caused by a defective compressor module thermo limiter (prevents overheating the compressor), replace it. ... Air Conditioners
