An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.Ĭould be other issues, but I would start with these. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. Switch on the power supply of the refrigerator. Turn the fridge off from the manual control panel. Leave the fridge unplugged for a few minutes. This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.Ģ. Following are some steps to reset the compressor: Deactivate the power of the fridge. If clutch is bad, compressor would need to be replaced (sold as one unit). Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. Both the refrigerator and the freezer are not staying cold. Additionally, the lights on the front face of the the ice maker were blinking and some have eventually just gone out. Each time it closed, it made a very loud and annoying 'bang'. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. 24th, the ice dispenser 'flap' started opening and closing on it's own about every 4 seconds. If it is not engaged, then your compressor clutch is probably going out. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. I would check the following possibilities:ġ. If this is not the problem, you'll need a set of AC gauges and the skill to use them. Go to Walmart and get two cans of r-134 and the inexpensive kit, and following their instructions, charge your system. There is a safety switch that prevents the clutch from operating if there is not enough freon in the system. If the clutch does engage, then you are probably low on freon. Warning: do this only for a second or two in order to see the clutch engage. You can pull out the relay, carefully remove the cover, reinsert the relay, and engage the compressor clutch by manually closing the relay contacts. A search of Google images will give you the location of the AC relay. If the clutch doesn't engage, which is the most likely situation, either you are low on freon, the AC clutch relay is inop, or AC compressor fuse is open (blown). If the clutch engages, you can be reasonably sure that the system has freon, and the electric circuit is OK. With the engine running, have an assistant turn on the AC while you observe the AC compressor clutch. The compressor is driven by the serpentine belt and is engaged and disengaged by an electric clutch mounted on the compressor drive pulley. If all you get is hot air there are several possibilities.
