TROUBLESHOOTING HEAT PUMP SYSTEMS…INDOOR / OUTDOOR TEMPS VS SUPERHEAT W/ FIXED ORIFICE SYSTEMS June 8, 2008

..If you look at a superheat charging chart for a fixed orifice system, you quickly see the required superheat varies with outdoor and indoor conditions. As the outdoor temperatures vary, so does the required superheat…pretty much the same relationship for indoor temperatures. Why? The net force pushing liquid through the metering device is the difference [...]

TROUBLESHOOTING HEAT PUMP SYSTEMS…R-22 VS R-410A April 18, 2008

Unless you’ve been living under a rock for the past several years, you know R-22 is on the way out and R-410A appears to be the manufacturer’s weapon of choice for heat pump and comfort cooling equipment. If you’ve already encountered a 410A system and had a less than pleasant experience, possibly attempting to correct [...]

TROUBLESHOOTING HEAT PUMP SYSTEMS…OPEN CONTROL VOLTAGE CIRCUITS April 16, 2008

One of the more frustrating and difficult situations with heat pump diagnostics is open circuits in the control wiring. There is a logical process to follow when attempting to locate the failure…

TROUBLESHOOTING HEAT PUMPS SYSTEMS…REFRIGERANT LEAK DETECTION DEVICES April 15, 2008

No doubt, my most frustrating service issue has been locating refrigerant leaks. And I’ll be the first to admit it was due to my own ignorance, from simply not doing a little research. I started out with a cold sensor technology electronic detector, bought a second cold sensor electronic detector and eventually concluded electronic detectors [...]

TROUBLESHOOTING HEAT PUMPS…DIAGNOSING PSC MOTORS April 13, 2008

A common failure with residential equipment condenser and blower motors is not actually the motor, but the run capacitor. Probably the majority of the time, the capacitors fail “open”…the motor can’t develop the necessary torque to actually begin rotation. So, it justs sits in a “stalled” condition, pulling above normal amps…the video gives some thoughts [...]

Some thought on combustion testing. When performing a combustion test, one of the most important concepts to understand is stability of the combustion process. If the combustion process is not stable, it is not safe. Once a flame is established, the burner should quickly reach study state operation and not be affected by factors external to it. While [...]
