Is your AC blowing heat air as an alternative of cool, refreshing air? One potential offender is a defective compressor. The compressor is the guts of your AC unit, chargeable for circulating refrigerant and eradicating warmth from the air. If it isn’t working accurately, your AC will not be capable of cool your property successfully. On this article, we’ll discover find out how to establish a damaged compressor and supply ideas for troubleshooting and restore.
Some of the widespread indicators of a failing compressor is a scarcity of cooling. In case your AC is operating however not blowing chilly air, it may very well be as a result of the compressor isn’t compressing the refrigerant correctly. This may be attributable to quite a lot of points, together with refrigerant leaks, electrical issues, or mechanical failure. One other symptom of a nasty compressor is a wierd noise coming from the outside unit. The compressor is a transferring half, so it is regular for it to make some noise. Nonetheless, if you happen to hear a loud grinding, squealing, or rattling noise, it may very well be an indication that the compressor is failing.
Should you suspect that your compressor could also be defective, it is necessary to name a certified HVAC technician for prognosis and restore. Making an attempt to repair a compressor your self may be harmful and will void your guarantee. A technician will be capable of take a look at the compressor and decide if it must be changed. In some circumstances, the compressor could possibly be repaired, however in different circumstances, substitute could also be crucial. In case your compressor is failing, it is necessary to have it repaired or changed as quickly as attainable to keep away from additional harm to your AC unit.
Figuring out the Sound of a Working Compressor
The compressor is an important part of any air con system. It’s chargeable for compressing refrigerant fuel and sending it by the remainder of the system. A working compressor will usually make a buzzing or buzzing sound. This sound is normally louder when the compressor is first beginning up, however it ought to steadily turn out to be quieter because the compressor reaches its working pace.
If the compressor is making an uncommon noise, it may very well be an indication that there’s a drawback. Listed here are among the commonest noises {that a} compressor could make and what they might imply:
| Noise | Doable Trigger |
|---|---|
| Buzzing or buzzing | Regular operation |
| Clicking | Unfastened or broken compressor |
| Whirring | Worn bearings |
| Screaming | Broken compressor |

4. Utilizing an Ammeter
Set an ammeter to the suitable present vary and join it to the compressor relay’s terminals. Make sure the meter’s polarity is appropriate.
5. Deciphering the Readings
Desk 1: Typical Compressor Present Draw
| Compressor Measurement | Present Draw (Amps) |
|---|---|
| 1-Ton | 4-8 |
| 1.5-Ton | 7-10 |
| 2-Ton | 9-12 |
| 2.5-Ton | 11-14 |
| 3-Ton | 13-16 |
Evaluate the measured present draw to those typical values. A considerably decrease present draw could point out a defective compressor, whereas the next draw may counsel an issue with {the electrical} circuit.
Measuring Compressor Temperature
A compressor that’s too sizzling or too chilly can point out an issue. To measure the compressor temperature, you have to a temperature gun.
Level the laser on the temperature gun within the heart of the compressor. Press the set off and maintain it till the temperature studying stabilizes. Report the temperature.
The traditional working temperature vary for a compressor is between 150-250°F (65-121°C). If the compressor temperature is exterior of this vary, you will need to have the compressor inspected by a certified technician.
The next desk gives a common guideline for deciphering compressor temperatures:
| Compressor Temperature | Doable Trigger |
|---|---|
| Lower than 150°F (65°C) | Compressor is undersized or refrigerant cost is low |
| 150-250°F (65-121°C) | Compressor is working usually |
| Larger than 250°F (121°C) | Compressor is overloaded, refrigerant cost is extreme, or compressor is failing |
It is very important be aware that the compressor temperature can range relying on the make and mannequin of the compressor, the ambient temperature, and the load positioned on the compressor. At all times seek the advice of your unit’s particular working directions for the right temperature vary and troubleshooting steps.
