Improperly programmed programmable thermostat.
Compressor not operating.
what causes compressor lockout in voager rooftop unit.
Call an HVAC repairman. You're probably low on freon and a protection system is keeping the compressor from burning up. Sounds like to me it is a protection device. Probably an internal overload on the compressor. Have you checked the outside coils they may be blocked with dirt? This would cause the compressor to go out on overload.
Try putting a sound blanket over the compressor. Will that make the compressor run hot?
the compressor is not running. Check your breakers.
near the compressor on the wall of the cooling condenser
It is normally caused by the "clutch" within the compressor unit itself slipping. The more you use it the worse it will get. Basically it keeps losing its grip. It can also be caused through a bad signal to the unit which would be the electrical aspect of it, however this is less common.
Hi, Outside unit means - Compressor and Condenser. 1. If compressor weight more- More power is required to do the same job as lighter compressor to get same work output. Life of the compressor has to be checked. 2. Condenser weight- the thickness of the condenser tubes is more then heat tranfer reduced. overall efficiency of system will reduced.
It is possible that the circuit breaker for the compressor unit is thrown (switched to "off"). Go outside to the compressor unit and follow the big cable up to the circuit breaker panel on the wall. If it is off, throw the switch to "on." If that is not the problem, something is probably wrong with the compressor unit. Turn off the breaker panel and call a repairman.
Yes your compressor comes when you set your thermostat to "Fan" setting and you have it on cool setting.
You can`t... There is normally no relay on the indoor unit that starts and stops the outdoor unit. The switching of the thermostat starts and stops the condensing unit, if it is not running, and the thermostat cooling contact is closed, the problem is outside.
A stuck compressor contactor. Do not turn off the indoor fan until you have either shut off the breaker or pulled the fuses to the outdoor unit and stopped the compressor, or damage may result.
