. It was around 40 degrees out. Before replacing the TIPM might want to ring out the energizing clutch wire to the TIPMs connector to be sure and make sure that wire isnt shorted to. Air Conditioner Compressor Clutch - 25 to 5 amps.
Nighttime amp readings 80 degrees ambient temp started at 10-something amps slowly creeping to 120 amps before reaching thermostat setpoint thermostat set to about 72. Air conditioning clutch energized at all times causing 3 amp draw. The compressor clutch also keeps the air conditioning from running constantly.
I checked the name plate on the ac and RLA for the compressor was 142. Windshield wipers - 2 to 10 amps depending on load. Automotive Air Conditioning Information Forum Archives Provided by www.
When current is passed through the coil it creates a strong magnetic field that pulls a splined hub into contact with the spinning pulley. Heated Seats - 3 to 4 amps per seat. But also the torque varies greatly with respect to pump shaft angle position.
Do not try any of what you see in this video at home. Hes dealt with the refrigerant R1234yf but not the AC compressor itself so I have a few questions. High running amps could mean a bad compressor.
Id just like some feedback. The coil contains a clamping diode to prevent voltage spikes when the clutch suddenly disengages. They divide the MCC by 144.
An AC compressor clutch coil is a. Especially since the whole heating circuit also uses that 75 amp fuse. The current draw of the coil is not normally shown but is typically 150-200 mA with a corresponding coil resistance of around 80-60 W.
This action engages the compressor. Im not sure if this tells you your compressor may be bad and maybe only the clutch coil itself. Air Conditioner Compressor Clutch - 25 to 5 amps.
An AC compressor clutch coil is a simple device made of fine windings of wire wrapped into a coil. Or a 12 amp draw 120 volts ac. Daytime amp readings on compressor 100 degrees Fahrenheit ambient temp started at 14-something amps slowly creeping to about 24-something before reaching thermostat setpoint.
Try again without holding the ceiling fan blades. If the TIPM controls the clutch that sucks and not cheap to replace. An AC compressor clutch coil is a simple device made of fine windings of wire wrapped into a coil.
Heated Seats - 3 to 4 amps per seat. Heater AC blower motor depends on load size and speed setting - 2 to 30 amps. When I check volts and amps through the harness to the compressor I get 12v and no amps not even enough to light up my test light.
What Is The Amp Draw Of A 5 HP Compressor. As can be seen below from the 04 FSM p24-13 the clutch coil amp draw should be 20-39 amps with system voltage between 115-125V. Sanden 508 amp draw.
I am trying to find a way to diagnose the clutch issue manually. Va914 on Fri June 04 2004 851 AM. Should I put a relay in-line between the thermostat and the 508.
However when I pulled amps on the unit it was 63. Power Windows - 3 amps. When you turn on the air conditioning the clutch engages and begins spinning to transfer the power.
There are 2 connectors for the AC compressor the C1 connector at the top and front and the C2 connector under and towards the back. Some compressor manufacturers such as Copeland use a different factor. This one gives instructions how how to properly check amp draw of the compressor in the AC or heat pump.
I cant tell by the wiring diagram how to tell what amp draw the clutch should use. Even at low speed you can probably estimate torque to pump shaft. I took an amp reading on my compressorAttention.
He did not check the charge and it is a 1-ton compressor. I am retrofitting a 508 into my system and have a Q. The issue is the AC clutch will NOT engage.
If your motor is going to draw too much current by whatever criteria you establish then use a belt and pulleys to reduce the RPM at the pump. A line thats too large or too small for your system can cause premature AC compressor failure. It takes at least two years of HVACR schooling to bec.
But can see if the clutch is ok the compressor turning real hard could put a strain on the clutch itself causing amps to increase. These TIPMs are great when the work but a PITA when it comes to troubleshooting problems as you found out. The AC compressor clutch is responsible for converting energy from the engine and delivering it to the compressor.
The current compressor is wired directly to the thermostat. I would think it would need less than 75 amps. Windshield wipers - 2 to 10 amps depending on load.
It does mean that using the nominal load it draws 115 Amps. But there are other causes which include. Similar current draw can occur in a DC coil of a solenoid a relay and even in our AC compressor clutch too.
If it is an air conditioner the load is 18600 BTU hours which is 56kW - the thermal energy it can draw out. Heater AC blower motor depends on load size and speed setting - 2 to 30 amps. Searching the Internet tells me that the average current draw for a 12V magnetic clutch is approx.
As can be seen below from the 04 FSM p24-13 the clutch coil amp draw should be 20-39 amps with system voltage between 115-125V. I called my two of my ASE Master Tech friends and both told me that 75 amps seemed excessive for an ac clutch. Less currentamps needed to get the motor rolling now.
If the RLA has any value it is to determine at what amperage draw the compressor overload will trip and to determine the fusecircuit breaker size and the wire. Customer wanted the ac unit to be on the transfer switch. Grab and hold your ceiling fan blades then turn it on.
Electric Power Steering - 2 to 40 amps depending on load. Overcharged system badweak capacitor low line voltage or dirty condenser coils. Subaru tribeca air conditioner not working.
I was wiring up a Relience 6 circuit transfer switch today. Shorting the contacts at the connector on the low side of course makes no difference. I have a 97 Merc Grand Marquis with 12V from the harness to the compressor but no clutch engagement.
However when you use the motor dont drive it more than 115 Amps in long term. Electric Power Steering - 2 to 40 amps depending on load. How much current does an AC compressor draw.
Dec 8 2018. Search Auto AC Forum Archives. Power Windows - 3 amps.
At 12 V this is 110 Amps.
