Can a faulty thermostat effect your central AC unit?
can a faluty thermostat affect your central ac working?
Central ac runs intermittently?
A central air conditioning unit will commonly turn on and off intermittently. To stop this, adjust the temperature on the thermostat or switch the unit either on or off rather than the automatic setting on the thermostat.
Why does the thermostat in central ac burn when changed from manual to automatic?
short in the wiring
Does the compressor come on if you have the fan only running on your home ac unit?
Yes your compressor comes when you set your thermostat to "Fan" setting and you have it on cool setting.
What could be wrong if your home AC blows cool air but not very cold?
check you thermostat for the temp setting
Does the ac need to be running when adding freon?
Yes it needs to be on,and set for the lowest temp,and highest fan setting.
Why do room air conditioners ice up easier that central air conditioning system?
Generally the thermostat setting is too low with the fan speed set at minimum or low, this results in the ac unit operating continuously and not cycling . The room ac unit may be undersized resulting in the ac cooling mode operating continuously so that the compressor does not cycle. Another reason could be that the refrigerant charge is insufficient. Finally, as the ac is visual, therefore icing up will be noticed. A central ac unit is usually out of sight externally to the dwelling or mounted on the roof.
Will the AC work if you remove the thermostat?
yes Thermostat has no effect on A/C
What is wrong if a old ac unit never shuts off when thermostat is in auto do you think its the relay?
The AC unit is fully controlled by the contactor. If the unit turns off by thermostat control such as setting tstat to off, the contactor is ok. The thermostat could be the problem though. yeah i understand that but when i say old unit i mean its so old that the thermostat only have two cables the red one and the white one! the auto and cont the unit has it in the indoor unit!!!
Heater and ac do not work?
Check the thermostat.
Heat anticipater setting?
Usually refers to the current (AC AMPS) that flows through the thermostat. Use an AC ammeter to measure the current across the (heat) terminals. Usually .1 - .9 AC amps. It is used to fool the furnace to shut off a little early so that the residual heat in the furnace won't increase the room temperature beyond the temperatur setting.
Can a bad thermostat make ac blow hot air?
No. The thermostat is not likely to be the cause.
