20 Most Recent Whirlwind FH-778 Air Conditioner - Page 10 Questions & Answers

If it shuts down completely, it is probably a safety device. Doubt if it's the t'stat. This sounds like something is overheating and the safety is shutting down the unit. The safety could be the fan delay/limit switch. Also, there are usually several "Thermal Disc" type safety devices located near and around the heat exchanger. These can go bad. In other words, they can "Trip" at a temperature lower than the rated temp the devices is supposed to trip.
I would look here for you problem. Good Luck

Is your husband a licensed contractor? If not alot of the hvac supplies stores will not sell to the general public. Hope this answers your question.

r22 will remain on the market.2010 is when it can no longer be produced.Just like has happened to r12....the price will go through the roof.

That sounds like the compressor is not kicking-in. Now you need a service tech to diagnose & locate the problem and solve it!

That was real deep diagnoses I'm betting the outside unit is the problem. check the outside for240-volts to the contactor if not backtrack for the lost voltages and remove the outside cover to check the little silver can (capacitor) for swollen at the top terminials, due to power surge.

Go to the supply house and ask for an in-line tap! SSSSSSSSSShhhhhhhhhh(the mechanic might had connected the wrong end of the hose,(one end has a hole and the other end has a valve stem depresser to depress the valve stem to let in-out freon.. Or the older type, you have a king valve and has to be turned to open or close the ports!) ssssshhhhhhhhh!!

What do you do ,when your under arms smells, you wash it and add deoderant! thnk-you very-much!

HEY_ 2 viable options suggests them self to me, 1 - low airflow ----------2 low on freon charge! Thank-you-very-much!

Well duprees, first you got to have the right instrumentation for charge freon to a a/c system, now, the charge line is the thick line, wich it means the suction line, the colder line, or the most robust line on the compressor.
Then, the system uses freon 22, the right charge, with the system on and the compressor running is 68.5 to 70 psi.
This should give to you about 40 degrees(farenheit) at the evaporator, the panel that gets cold in the system.
This pressure should be at the low side, meaning thicker line in the compressor unit.
Hope this help you......



Good luck.......

Check your filters first. Replace if needed. Also check that the evaporator fan or blower fan in the furnace is running. If this does not fix it you most likely have a low refrigerant charge.

You need to have the system evacuated to fix this leak. First thing is for safty reasons, for your protection and refrigerant release. second is to make sure no contaminates are released inside your system. The tech should recover the refrigerant fix the leak, then purge with nitrogen, then pull a deep vaccum to 500 microns and it should hold for 20 mins. then he should recharge the system with refrigerant.

Hope this helps

Inside fan motor should be checked. Take a piece of paper and hold it to your return. If it isn't pulling the paper in you have a bad fan motor. Also check to see if the large line on your outside unit has ice.

Raise your thermosat to about 78. Also check to make sure the thermostat is set to auto and not on...

the large tube. it should be very cold
and the high side should be very warm but not hot.
if very hot you are leaking and low on freon.

Try A.B. May they are out of Kansas City but they will travel up to 90 miles I have heard.

you need to use a meter to ensure that you are getting control voltage from the xfrmr. Also check it at the coil side of the contactor if you feel comfortable doing this but be careful of the line voltage side. If you are getting power on the coil side of the contactor usually a 24v signal from the tstat from the area labeled y and the contactor is not pulling in most likely you will need to replace the contactor. If the contactor is pulling in verify the amp draw on the compressor with the tag.

I have a haier unit and last night the led went crazy it has totally stop working now and the LED just shows E1 I have tried unplugging it and resetting the button on the plug and nothing has helped this unit is less than a year old. Please help if you can....

We tend to only get new hoses when they split ot a leak is suspected.
