High temperature discharge air is caused by leaking reed valves or leaking head gaskets. Another indication of leaking head parts is that it takes longer to fill than usual or the compressor will not reach cut-out pressure. Good luck

My air compressor show continusly the alarm NO CONTROL POWER

No Control power is often caused by high airend temp or a faulty High AirTemp. switch(IATS Switch i.e High Air Temperature Switch). I suspect the IATS switch is bad and opening prematurely/coolent level not suffecent or bad filter condition because the att. temp. probe located next to the switch is set to give a temp alarm and shut down the compressor at 228 degrees.The hat switch is located in the end of the airend and should have a 1/2 " flex conduit attached to it. When this switch opens it cuts control power and series to emergentcy switch having two NC connection but if press emergency it gives alram emergency but if you remove cable 36 inintellisys control pannel. Thus the controller issues a No control power . This switch is set to open at 245 degrees. If faulty it may open at 150, 180, 200. Anything but what it is set at. You can check this switch with a meter. When the unit trips simply test for 110 volts at the switch or in the control panel if familiar with wiring . please be very careful while in any electrical panel.. 110 volts in, 110 volts out. NO 110 volts out or on one leg of the switch means its bad and should be replaced.After it cools for a while the compressor will run again.

After running for a few hours it gets hot and shuts down but runs fine every morning

Without more info I will have to give you several things to look at. Typically during the hot months rotary units experience temperature shut downs due to the following. Dirty oil coolers. Blowing them out with air my help some but ideally they need to be washed using a degreaser solution. Location. during the hot months poor air flow/ air removal may let heat from the compressor build up in or under the cover or room. This hot air gets drawn in by the compressor and raises the compressor temperature. The cycle continues until the compressor shuts down on high air temp. Maintenance. Poor maintenance on rotary screw compressors leads to shut downs on high temp, high air temps then play havoc on dryers which causes moisture in the air system. Maintenance items that need replacing regularly ( about 2000 hrs) oil filter, air filter, Depending on type of oil used change 2000 to 8000 hrs, seperator @ 8000 hrs. Also the amont element will cause high temps if bad. It is located where the three oil lines come together. There should be 4 screws that hold the cover on. the cover also has a hose connected to it and located close to the oil cooler. This amont element acts like the thermostat in your car. it lets oil bypass the oil cooler or causes more oil to go thru the cooler. the cooler oil and bypass oil mixes and maintains a certain temp. air end temp should run about 195 F and injected temp about 165 F. hope this helps. if you can give more detailed info I can get you closer to your problem.

Temp off air coming out of register 74 degrees suction line temp is 42 degrees but high side line isnt warm dont look like it is wanting to take freon either compressor is running new system low side is...

Hello, what is your high side pressure? A bad compressor will show abnormally high low side pressure with abnormally low high side pressure. That 45 low side pressure is low And superheat high. If you high side pressure is normal toma little above normal but the low side remains low you have a restriction in the system, that might be why it's not taking in tne freon. Let me know you high side pressure

My 185 ingersoll rand tow behind compressor shuts down when I open the valve to blow out sprinkler system...why

I worked at a tool rental store while attending college and noticed that IR compressors would shut down for a variety of safety reasons. Most common was low oil (engine), high temp (engine) and high air temp (compressor) and safety valve measuring access flow or free flow as if the hose becomes disconnected from tool (OSHA safety). Check all the safety control features of your unit for possible answer. Good luck

No cool 80 supply temp

That is a high suction pressure should be running about 46 psig and head pressure should be amibent temp or outside temp and add 25 to it. that will give you approximate head temp. sounds like you have a dirty condenser I would clean it. Check your amp draw on your compressor if its high then I would check for dirty condenser. You can clean it with a stiff hair brush go up and down do not go sideways because you can damage your fins on the coil. Then take a water hose and wash it out. turn off the power to the unit before cleaning do not clean with compressor running. turn off the breaker box. I hope this helps.

My rotary screw air compressor model SSREP100H

It's just too hot. Blow out the radiator weekly. There is an oil temp switch that might need replaced but the radiator is the most common problem with screw compressors. You can check the settings in the control panel, where you turn it on and off. It should be set for a high temp of 185°.

My low side is 90psig and high side 250 psig what is going on

If it is very hot in the house the suction will be high but not that high. If you have a 13 seer inside and a 10 seer outside your suction can be that high if you don't lower fan speed. Does your unit coll ok. Another reason if it is not cooling well is bad valve in compressor but the compressor would going out on internal overload because of getting to hot. If you have TXV metering device it could be stuck open. Check sub cooling. Put a thermometer on the 3/8 line and measure the difference between that temp and the guage temp. Look at your pressure and the temp reading is nest to the pressure. The difference should be between 12 and 16 degrees. Measure Large line temp for superheat difference should be between. 12 and 16 degrees. Feed back please
