My bonaire evaporative cooler cycles from high to low fan speeds when set in the cool mode. It works fine at the required speed setting when just the fan (no water) is selected. It also dumps water immediatly the cooling cycle is turned off rather than holding it for about 40Min as it should. Sounds like a controller problem, but I'm not sure if it would be the touch pad or the board up on the roof mounted unit.

The fan speed in my mini split a/c indoor unit is abnormaly low even when set in High speed mode. This unit also has a powerful mode to raise the speed beyond High for 15 minutes, but it is not working either. I replaced the fan motor, the power supply board and the main board to no avail. Any help will be appreciated.
Please change the fan capacitor,all will be ok afterwards. ... Air Conditioners
This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.

Amana PTAC Unit is not producing heat. Fan works fine. can not locate manual reset for heat although a label on the unit says there is one. I have an Amana pth153b35ae ptac unit that the heat will not come on. The compressor will run in the cooling mode but not in heat mode. I verified the switching valve is working and the capacitor seems to be fine as the compressor will run in cooling mode. The thermostats seem to be functional because relays can be heard clearly when changing temperature se

1996 Coleman Model 7333C8876. Have 2 units on our Motor Home one day it was hot so I had both units running controlled by a Electronic Climate Control system. It got cool in the evening so I turned them off. The next day when i fired them both up on high the rear was fine. But the front will only cool on Low. The fan will not run on high and you can hear a slight noise coming from the unit. But the fan will not run on high.

I have 2 dometic roof top units on a 2002 MH that I recently purchased. 1 of the units only runs on high speed, the stat has a high low switch, the unit cools fine. The second unit, the comp starts, but the fan only hums, the shaft turns fine. I switched the start relay from the other unit, same result. I suspect that the start winding is open, but haven't checked yet. I am not opposed to replacing the unit because of age, condition of roof cover,and suspected cost of parts. Would appreciate any
Hi, unit # 2 sounds as though the run capacitor may be open, shorted, ect.When you say you changed relay, I assume you were talking about the capacitor. If the motor didn't run when you changed it, you do have a bad winding, or open as it just hums. ... Dometic Air Conditioners
Sharp AF-R1108X Thru-Wall/Window Air Conditioner was working fine all summer. The past 2 days were extremely hot out. the unit was working around the clock. the unit was in low cool and keeping up fine. Then it started making beeping noises and going into energy saving mode and cycling the unit on and off constantly and would not allow me to turn it off by using the selector button. I had to unplug the unit to turn it off. I left it off for about ten min. hoping it would reset it self. I turned

Great site. I have a Simplicity SPAC 8499-5 Portable Air Conditioner and it was working fine up until yesterday (~2 years old). The unit is running and the fan operational but while the green light for Cool/Dry is illuminated that actually cooling unit for the air conditioner is not kicking in. The system is just blowing air (like in Fan) mode. I have checked the water reservoir and it is empty and placed properly in the unit so the switch is engaged but no AC.

I have a Sanyo khs1271 that is about three years old. For the last six months it has been making a high pitch chirping sound in both heating and cooling modes. I suspect the problem is the fan on the indoor unit as the chirping only occurs when the fan speed is on high. So far, the only solution to the problem has been to turn it on quiet mode, which reduces the fan speed and thus makes the unit's ability to heat or cool less effective. Does anyone know how to access the fan on the indoor unit

I have a 8 years old window ac. It's working quite ok. I just want to know which mode is safer low cool or high cool when humidity is high but temp. is about 32-34 degree celcius. Technican advised me to run in high cool mode for some time n then switch is off, but i want long hr. running in low cool mode which is quite comfortable. Kindly advise.
Its not a mater of safety. Its only a matter of witch is best for you. If you want to maintain the temp then leave it on low temp. If you want to save money then you can switch it to power saver mode on high to bring the temp down. Hope this helps. G ... Air Conditioners
