Understand the effects of temperature and humidity changes . The wires coming to the gas valve from the board are in a harness. November 23, … Popular Items. The stock market had crashed just a few years before he was born and Stanley grew up in in New York City. This means that when the suction gas (vapor) travels down the line and enters the compressor crankcase it also cools the motor and internal components of the compressor. It is simply the temperature increase on the refrigerant once it has become fully vapor. Every good residential tech should have a little plastic container with various brands and sizes of piston in it in case you find one that is the wrong size or worn down from improper seating. Listen on Apple Podcasts. The Trane style has a much smaller size and is directional. If there’s no way for you to disconnect wires at either end (which should never happen as far as I know…) you could always cut the wire and check your voltage in the wire itself. All partner HVAC trade schools are accredited and have financial aid assistance for students who qualify.

In Florida, there are not many gas furnaces, At least not as many as up North. I’ve done podcasts and videos about how air can “hold” less moisture when it is cooler and more when it is hotter. Many residential techs get confused when they see these multi-position valves in larger equipment and Andrew does a great job of demonstrating the basics in this video. This position provides full operational flow through the valve body but is closed to the access port. The backed up condensate will simply end up blocking that port and the switch will no longer be able to ”feel” the vacuum, the contacts won’t make and you will get an error (pressure switch not closing or stuck open). HVAC School - For Techs, By Techs. iPhone. It was either the board or the valve. Details About Us.

So the contacts will stay closed, until the next call for heat. Below is a link to a podcast with Bryan Orr from HVAC School. When a piston is restricted and the system is a heat pump with a liquid line filter/drier properly installed, we will often alternate the system into cool and heat and see if that will break free the contaminants and catch it in the line drier. One thing to know about 80% gas furnaces with cased evaporator coils is that you can often check the evaporator coil by removing the high limit and running an inspection camera up through the opening. Clay Stevens, AHR Expo Show Manager. With the valve open (so, closed circuit) around 200-300mV. We measure superheat (generally) on the suction line exiting the evaporator coil and it helps us understand a few things. Heating, Ventilating & Air Conditioning Service . Remember, this chart ONLY applies to fixed orifice systems. This is done in TXVs by means of an internal or external check valve but with a piston, the piston itself is allowed to slide in the housing allowing restricted flow in one direction and unrestricted flow in the other. This certainly helps us remember but it isn’t really how it works. I would say however that in three and a half years I haven’t had to replace a fireplace gas valve. If your thermopile gives enough voltage but the valve won’t open, check your switch/tstat and even the wire itself for any significant resistance or short. © 2017 HVAC School All Rights Reserved.

Otherwise, the piston should be removed, inspected and cleaned or replaced and a new line drier installed. If your wires are all in a harness with a big fat connector on the board, there’s a good chance you won’t be able to pull it off and diagnose on the board pins, because by removing the connector you remove most or all of the safety circuits. Heating, Ventilating & Air Conditioning Service. If it’s just a standard 24v valve with 2 or 3 terminals (Common + hot or common + low and high solenoids) just pull the wires off (or connector) at the valve and you have to check for 24V on the wire across common and hot.

But I’d probably even replace a switch/tstat before I condemn the valve regardless, just to be sure, just because changing those valves in most cases is a total pain in the butt. If you were […] The post A Shocking Discovery appeared first on Bryan Orr. In this episode we review application based system selection considerations for VRF/VRV systems. Most “active” metering devices are designed to output a set superheat (or tight range) at the outlet of the evaporator coil if the valve is provided with a full liquid line of a high enough pressure liquid (often at least 100 PSIG higher than the valve outlet / evaporator pressure).

If your thermopile alone doesn’t produce enough mV’s, check your pilot flame. Otherwise, you are stuck removing the entire blower assembly… and that’s no fun at all. #3 – We can ensure our compressor stays cool by measuring superheat. If it’s one of those Honeywell SmartValves, then that’s another story entirely. On both TEV / EEV systems and fixed orifice systems (piston / cap tube) you will notice that when the air (or fluid) going over the evaporator coil has less heat, or when there is less air flow (or fluid flow) over the evaporator coil the suction pressure will drop. Keep it up! The physical exterior dimensions of the piston must be the same as all the others for that brand/series otherwise it will not fit properly. Front seated closes the valve and shuts off flow through the system at that point while remaining open to the port. The air around us is all superheated!

A hot motor not only is more susceptible to winding breakdown but also to bearing/lubricant failure. This will result in a pressure drop and an undesired restriction similar to a clogged liquid line filter drier. Size. Measuring superheat along with suction pressure gives us the confidence that the compressor will be properly cooled. - Heating, Ventilation, and Air Conditioning is the technology and trade of indoor environmental control. HVAC … If it is too high the valve is too far closed. On a fixed orifice system as the load drops so will the superheat. In this series of articles we will explore the, “What should my _______ be?” questions one at time and hopefully learn some things along the way. Rocket Science Cap.
