When it comes to choosing a multimeter for servicing refrigeration systems, there are a lot of choices on the market. Careful planning should go into selecting the right meter.
In this troubleshooting problem, the customer’s general definition of the situation gets more specific when you arrive at the site and discover that the reason there is no heat is because although the burners ignite on a call for heat, the air handling system never starts, and the system’s limit control shuts the furnace down.
Fluke Corp. introduces the Fluke® VT02 Visual IR Thermometer, a troubleshooting camera with infrared heat map. This one tool combines the visual insight of a thermal imager with the point-and-shoot convenience of an infrared thermometer.
Interplay Energy develops 3-D interactive simulation training and testing applications. The company was approached about developing a companion program for the HVACR textbook, Refrigeration & Air Conditioning Technology. The end result is the new Delmar Online Training Simulation: HVAC from Interplay Energy.
Bob and Tim have gotten together after work to discuss the oil furnace service call that they were on earlier in the day. Bob had asked Tim if he would be willing to stay after work and review the call and Tim readily agreed.
Onset, a leading supplier of data loggers, announced that the company will be hosting a one-hour online training course, “Economizer Diagnostics Using Data Loggers,” on Wednesday, Dec. 12, 2012 at 2 p.m. EST.
Bob and Tim were on their way to a no heat call. It was an oil heat application and Tim was anxious to work on an oil system. He had not seen an actual oil heat installation, only in the school lab. Those are great, but not like the real thing at a customer’s house.
Today more and more systems are incorporating microprocessor controllers into their design. Troubleshooting the operation of these controllers can be a little tricky at times, but if broken down into sections it can be easier to handle.
In this month’s troubleshooting problem we have a customer who can only tell us that their heat pump “isn’t working” and “the temperature in the building isn’t right.” When you arrive, you confirm the system isn’t operating properly. The indoor fan motor is running normally, but the building temperature is far from the thermostat set-point.
