I have a gulf stream pool heat pump. It tries to start and runs for a few seconds then shuts down. it will do this like 3 times then stops. will repeat about every 10 minutes. was working find 2 days...

Hi, sounds as though you may have several problems, or I should say there are several things that will cause a unit to short cycle and then shut down. First of all, the head pressure in the system if it is getting to high, will cause this unit to shut off on its high pressure switch. When it shuts off the pressure will drop and the switch will reset on auto and start again just to do the same again. Shut the power off to this unit. Take a water hose and give the coil that surrounds the condenser a good washing out. Be careful not to bend the fins down on it as this will prevent air from being released to the outside air. Use a nozzle and adjust it as needed. If the problem was a head pressure problem, this will stop it from short cycling. If I were on site with my manifold gauges, I would no right away if it was a head pressure problem. After doing this, if it starts to do the same thing again, being low on freon will also cause a system to short cycle. If it was fine 2 days ago, I doubt if it is low on charge. Make sure the outdoor fan is up and running as this will cause it to go off on high pressure cut-out. This does sound like your problem. What happens is the coil gets dirty over time and the air can't be removed properly. The compressor will start and the pressures will rise very fast and shut of with in a few seconds. After a few attempts to run, the compressor will lock out on internal overload until it cools off and resets its self. It may take 5 to 30 minutes for it to start and try again. Do the cleaning process I have asked not getting water directly into the electrical control panel, but give this coil a good washing. If this system has a return air filter somewhere, make sure it is clean. Do this and get back to me and let me no if this solved or helped at all. If not, we can go from there. Just look me up with my user name. I do believe its just a plugged condenser coil. The symptoms are as you describe to me. Please get back to me.
I hope the best to you,

Desa TT30G Heater turns in to a blow torch

hi there
OK i read your report. when this happens again adjust the valve until you don't hear the blow torch noise. Because you could have had your valve open to far and that would make that noise. Try that and let me know.Thank you for writing to fix ya.

Best Regards Richard

How do I clean a flame sensor on a 1993 Lennox Whisper Heat furnace. It heats,then the gas valve clicks and the flame briefly stops and starts again then the valve clicks again and the flame briefly stops...

You can sand the flame sensor but it sounds like another problem. Sounds like a limit switch or something in the control circuit, You need to have a service tech look at this. Ask for free estimate on repair. I have worked on hundreds of these units and they are sometimes tricky to work on. Lenox has come up with new controls for the whisper heat furnace to replace the old ones. If the flame sensor is bad the unit will try to light a few times and lock out and you ahve to kull power to the furnace to reset. If this is whats happening clean the sensor nd you should be ok If not you need help from a service tech.Rus

Won't srtart

Check at the gas valve to see if you are getting power to the terminals after you hear the click shortly before the ignitor stops. If no voltage ...replace the board.
Sequence is

induction fan on, if pressure switch is reading ok condition---->

Ignitor is powered for up to 20 seconds (depends on model) ----->

Gas valve is energized ----> if flame is present everything just works away, if no flame in 3 seconds sequence starts over for set number of tries or continuously (again depending on the model)

Hope this helps

if 23/27 volts is present at gas valve then replace valve but bad valve is not very common usually, its the board.
