Heavy Duty A/C Best Practices: Preventative Maintenance, Diagnostics & How To Procedures
Driven by competition, computer aided design, a focus on quality and several other factors, mechanical reliability is at all time high. As a result heavy-duty A/C components rarely fail ! In fact, components mainly fail because of contaminated refrigerant oil and general lack of preventive maintenance. 

As the A/C season kicks into high gear we continue sharing our series on A/C Best practices. Lets begin with a quick recap of what we’ve covered, before introducing this months features in ATCNEWS and ATCTV.
In March we offered a A/C Preventative Maintenance Schedule along with a video on Basic Troubleshooting. In April we shared The Importance of a System Inspection and a supporting video on How To and Which Components to Inspect.

This month in ATCNEWS we feature How To Troubleshoot the A/C Electrical System and How to Inspect an A/C Compressor  while on ATCTV we provide a supporting video Examining Compressor Failures. We  hope you find this series informative and the overall content via these channels helpful.

How to inspect an A/C Compressor

Before you pull the A/C compressor from a heavy-duty vehicle, take these steps to confirm that it really needs replacing:

1. Is The Compressor Rotation Smooth?
With the vehicle off, turn the compressor shaft with a 14-mm socket. If you feel grinding or hanging as you rotate the shaft, it’s probably due to broken components within the compressor. If the rotation is smooth, move on to Step 2.
2. Is The Coil Getting More Than 11.5 Volts?
Take a reading with the engine running and the clutch engaged. If there’s insufficient voltage, get to work on that. Otherwise, move on to Step 3.
3. Is The Coil Resistance Between 2.8 And 4.4 Ohms?
Any resistance outside this range will prevent the clutch from engaging or will cause used circuits to open. If the answer is yes, continue to Step 4.
4. Is The Compressor Able To Produce 350 Psig Or More?
If not, leave the compressor where it is. The system may have a low refrigerant charge because of a leak that needs repair, or a high-side blockage that limits refrigerant flow to the compressor.

Tech Tips from Red Dot
” We see lots of compressors that are returned fully functional and therefore not warrantable.
Get the diagnosis right. Perform a simple compressor function check before you pull the component from the vehicle.”

How to troubleshoot your A/C Electrical system

Tech Tips from Red Dot

On any vehicle, and virtually any system, electrical problems are among the hardest to troubleshoot. If you suspect an electrical problem with the A/C system, here’s a two-stage inspection routine that virtually anyone can do with no special tools or skills:

1. Inspect Electrical Connections

As you perform a visual inspection under the hood (cab) and/or at the rooftop condenser, take a moment to check all electrical connections both visually and by feel. Make sure all leads and wires are properly supported and securely connected, and that there’s no corrosion or grime on the leads or connectors.

2. Check Electrical Current Flow and Device Functions

Perform the following steps to check current flow and electrical device functions:

  • Turn on the ignition. 
  • Turn on the A/C system. This will power the thermostat and clutch. If it does not come on, use the A/C mode switch to check the leads to the switch. You should hear a “click” from the thermostat and hear the clutch drive plate “snap” against the clutch pulley. 
  • Check fuses. If all the connections are clean and tight and there’s still a failure, check the fuses in-cab as well as in-line.
  • Check A/C clutch engagement. Since you can’t see and may not hear the clutch engage, get out and look at the clutch. If it’s engaged, you will see that the drive plate is against the pulley and not slightly spaced from it. If you aren’t sure the clutch is engaged, look for the lead wire connector near the clutch. Break and close that connection. The clutch will disengage and engage again.
  • Test blower speed operation. Some systems have a common switch that turns on the air conditioner and powers the blower motor. Test blower speed operation by adjusting this or the separate blower control switch. Feeling the air flow from the ducts or note blower sound (speed) changes.
  • Inspect roof-mounted condensers. Don’t forget to inspect roof-mounted condensers and A/C units for dirt and debris. Be sure the condenser fan(s) are working properly and all parts and electrical connections are securely fastened. The roof-mounted condenser fans may come on when the system is turned on. Like the thermostat and most clutches, the normal on-off cycling action can not be observed until the engine is running with the A/C system on.

Once your visual inspection is complete, talk to a qualified A/C technician about what you found. Your troubleshooting efforts will be rewarded with a speedier repair and perhaps a lower repair bill.

Thermistor Kit

What is a Thermistor ?
An electrical resistor whose resistance is greatly reduced by heating, used for measurement and control. Thermistors, derived from the term THERMaIly sensitive reslSTORS, are a very accurate and cost- effective sensor for measuring temperature. 

Your HVAC Thermistor can be replaced with #1400K for Quicker Installation and Less Hassle! 
Our Kit contains “First Fit OE Products”  for longer life solutions to today’s A/C problems.
