    With tstat off the wall wire nut red green and yellow. That's power, indoor fan and compressor. Make sure it is cooling, not heating and the compressor is running. If it is not cooling and the compressor is running add the orange wire to the bunch and try again. Once you figure out the cooling. WRITE DOWN WHAT WIRES YOU USED TO MAKE IT COOL and message me back. Remember to turn power off to AHU when messing with the tstat wires.

Make certain you understand thermostats come setup for gas, so pay attention to what your heat/cool unit is, that's very important, also make sure to shut off the power to your system before removing the thermostat.

I have a 2001 Suzuki Intruder VS800. it has a loud slapping noise. It does it at the beginning of start up then goes away until it warms up. Within a matter of minutes the back cylinder is heated up.

The back cylinder usually heats quicker and runs hotter and consequently is the first to develop problems. If you think the back cylinder is abnormally hot abnormally quicker there is probably a problem that is likely to manifest as a reduction in power, smoothness, economy and possibly strange or unusual noises.

It would be well to try and trace the noise using a stethoscope, sonoscope or similar device. If the noise seems to be originating from the back cylinder it should be thoroughly checked - coolant circulation, compression, cylinder leakage, fuel-air mix, etc.

There may be air trapped in the cooling system. If no air bleed on the thermostat housing, or right beside it, start engine at cold, remove radiator cap, and let it idle until warmed up and the thermostat opens fully. When at operating temperature, shut off the car, check coolant level, and put the cap back on. See if that removes any trapped air.

The heater in my Passat doesn't blow very hot air -- just warm.

This happened to my Passat, and little by little the air kept getting colder and colder until there was no heat left....I just took it in to get looked at- The heating core is gone- the part itself not that expensive, but since they need to take apart the entire dash to replace, the total job is like $800, $700 of that is labor!

Lg window-type ac

Most little window units are mainly for 300-500 Square foot rooms.
Should be putting around 80-105 degrees top out of those little units, Make sure that your thermostat is set for heat rather then the normal setting of cooling (Turn more towards Heat) also if you have a fan setting you may want to try lowering the fan to low speed vs high fan, which should give you more heat.
Make sure the Filter is clean as well as the coils behind the filter or it will shut down the heaters quicker due to lack of air, shutting down your T-stat and bi-metals quicker.

Good luck!

Projector keeps shutting off and red light comes on

We had a projector at our church that was hooked up to a light switch to turn it on or off and it kept burning the bulbs out. We had an expert come in and look over our situation and he said When you are finished with the projector let the fan keep blowing until the unit cools down. Ours had a switch for the bulb as well as one for the fan. We turned out the bulb and left the fan on for an extra ten to fifteen minutes. That let the bulb cool down gradually If you just cut the power the bulb over heats and will burn out. Yes turning on for a few minutes will burn it our quicker as well. Hope this helps.

On off cycling, little air flow, little heat

We had the same problem with the same furnace, CODE 32 DISPLAYED ON THE LEDS. I fixed it by cutting the air inlet pipe and using a hair dryer to supply heated combustion air to the furnace. Once I did that it started to run more and more until it finally heated the house up and works fine, so far so good.

We had a severe drop in temps, sunday it was 40 and rain and that night it dropped to -5 I suspect those conditions contributed to the problem. Wife observed this has never occurred before in 14 years of operation.

2004 Gmc Envoy XUV A/C problems

Hi, do you turn the AC as soon as you start the car? If this is the case yes if will blow hot until the AC kicks in. What the ac does is not put cold air in to the vehicle it removes the heat from the air, so it does take time for it to do this.A little trick for a bit quicker is to roll down a window these just helps. I read that once it starts getting cold it stays cold is this right? Once it stays cold have you notice that if you stop for just like running into the store and you start the car back up is it still cold or does the problem starts over? Hope this helps some please let me know.

Chech engin light secondary air pump

The SAI (secondary air pump) comes on for 30-45 seconds when you first start the engine if the coolant is under 85 deg F. It pumps air through the head into the exhaust. It's purpose is to supply extra oxygen to the cats to heat them up quicker and reduce emissions. It should have no real effect on engine performance, but does help bring engine temps up quicker making the engine more efficient.
