R22 unit running at 160/58. Took bulb out climbed to 61 on suction then right back to 58. Replaced txv. Charged to 220 head, suction stays at 60. Clean coil, no filter, good airflow. Ideas?????


Sounds like bad valves in the compressor.
A good indicator is how fast the pressure changes when you shut the compressor off. It should take several seconds for the suction pressure to rise. If it's immediate, then expect a bad valve.

The half of my house where the furnace is is hot. So there is hot air coming from the vents. (some of them). Half of the kitchen living room bathroom and 3 bedrooms and the hallway are blowing cold air.


where is the duct work located? In an attic, crawlspace? It sounds as if part of the system is disconnected. Are the outlets at the floor or in the ceiling? Is the duct work insulated? Can you take actual air temperatures at the outlets?

Unit will not heat, change batteries controller cleaned filters etc. Still blowing COLD air


Check the thermostat setting...in the auto machines, with a reversing valve, there is no heating or cooling, generally, in the sensing temperature band of 19 Deg C to 22 Deg C and it only works on blower mode, re-circulating the room air. When the sensing temperature goes below 17 deg C, it works on heating and when the sensing temperature goes above 24 deg C, it works on cooling

Furance blower works, ignitor come on for a short time we hear a click ignitor goes out blower runs for a short time ignitor come again but gas not coming on. What is wrong.


The ignitor needs to get up to a predetermined temperature prior to opening up the gas valve, you could have a weak ignitor. You need to see if the PC board is sending 24 volts to gas valve. If it is but no gas, bad gas valve. If not, bad ignitor or bad PC board. I would change out the ignitor first since it is a wear item as well as the cheapest component.

I have no hot water, in fact no water at all is coming through the hot taps in bathroom or kitchen. I have cold water and the central heating is working fine. What do you think the problem might be?


is there a separate water heater for those rooms? sounds like there could be a valve turned off. or the pipes are the old style galvanized and have plugged up. does any of this help lead you in the right direction?

My Rinnai 24 will only start when I use the the hot water in the kitchen (which is closer to the heater). If I open any of the hot water taps in the bathroom it doesn't work.. I have to start the hot water...


Looks like your recirculation pump might be bad. If your opening a valve close enough to the heater and it comes on, It sounds like it's giving your pressure switch a false reading and allowing it to come one while the farther away you get, it is not enough line pressure to overcome the safety's of the heater.

I have hot water in my bathroom sink,but not to my shower/bathtub all of a sudden.I went and checked the line and felt it,still plenty hot.I turned the valve off and back on,came back inside and had hot...


You don't indicate what kind of valve(s) you have in your shower/bathtub.

It is sometimes the case, when you have separate hot and cold valves that use the traditional flat washer, the rubber/viton washer wears over time and actually becomes cut, such that a part of the washer protrudes from the valve face.

Hot water will cause the distorted washer to expand. Consequently, as more and hotter water flows through the valve, the washer expands to the point where it constricts the flow of hot water.

Replace the washer, at least on the hot water valve.

Have a Amana a/c heater central furnace. Model number PGA30R0452A. The a/c part works fine. The heater part does not turn on sometimes. We have to keep turning it on and off to get to work. No matter what...


When you change from cooling to heating the fan will not come on immediately. A solenoid valve is energized (check that it is working) and operates a reverse valve, changing the gas flow in the system. It takes a few minutes for the system to build up sufficient heat and then the fan will come on. The humming sound is very likely coming from the solenoid valve. Make sure the air filters are clean. Obstruction caused by dirty air filter can prevent the air sensor from sensing the return air temperature.

Hot water system keeps going over the relief valve, Have changed it twice and still does it?


Check the hot water temperature setting, maybe its too high! or raise the psi relief valve by buying a higher setting! Thank-you-very- much!

I have a GE Hot water heater which is about 1 1/2 yrs old. 3 days ago the overflow valve started spewing water. I cut off the cold water and about 2 hrs later everything was fine. Now again the same...


The overflow valve as you termed it is operated by two factors. Temperature which would mean that the Bottom thermostat may be malfunctioning. Pressure which is not as likely, Lifts at about 150 PSI. Check water temperature. If the temperature is to high the problem is with the setting or the themostatic control may need to be replaced.

When you draw hot water the top thermostat takes control and cuts power to the lower thermostat. When the top thermostat is satisfied the control is changed to the bottom thermostat. The contacts on the bottom thermaostat could be welded together.
