Re: thermostat ?

The unit doesnt blow out continual cool air, it blows out cool air for 5 minutes, then stops, and after 10 minutes it starts blowing out cool air again. The room never gets cool like this.

It was working fine last year, nice and continual cool air, i cleaned the filter, is there anything else i can do?

Re: thermostat ?

The Air conditioner are good only the adjustment of thermostat are the problem, select the thermostat in lower #3 you observe the thermostat will off in such time temperature reach to #3 If you full adjustment the compressor will not off.
In fan selector the compressor will autamatic off because no connection attached fan only .

My domestic rv ac unit reaches the temp setpoint and the compressor shuts off but not the fan, it just keeps on running. Is this normal or should the fan shut off also?

Set fan setting to auto and not high or low setting. Fan will cycle with compressor after setting set to auto or " au" if a digital thermostat.

I have a 16 SEER Goodman air conditioner and during the morning hours, temperature ranging 75 degrees outside, the compressor comes on but not the outside fan. It only runs for a minute and a half then...

The fan is shutting off in order to maintain head pressure when the outdoor temperature is low. This is common on 16 seer and above systems. It helps your system be more efficient.

Dometic unit cools great but compressor does not cut off when desired temperature is reached. The thermostat is on wall. The fan will cutoff at proper temperature but the compressor keeps humming and...

Hi, as you know the thermostat controls the unit. Here's what you need to do first. Go to your thermostat on the wall, pull off the cover. You are looking for the main control wires that come in from the back to connect to the screw terminals. Don't be afraid of shock as these are millivolt wiring connections.You say the fan shuts off but the compressor keeps running causing it to ice up. You need to get a screw driver and disconnect the wires from this stat. This should cause the compressor, fan, and all to shut down. If it does, you know that your thermostat is faulty and you will need to make your self a drawing on the wire connections, remove the stat, and you can get a new one at a RV sales and parts house.Find your breaker box where your main wiring comes in and shut off the a/c breaker if you like. Now, if the compressor keeps running after you disconnect it from the thermostat, then somewhere from the stat to the controls on the top have a hot wire that is touching somewhere causing the compressor to be energized all of the time. If you can go up top and find where this thermostat wire comes in, look it over good to see if the red is touching the yellow wire some where. I believe you just have a faulty stat at this point. Do what I asked on the stat, disconnect it completely, and we will go from there. You can get back to me by leaving a comment under my user name. Please let me know and we will take care of this problem.

no both the options A and B which you gave cannot be done.yes option B is possible in some form.but in this case fan will not shut down and this will burn the fan motor and even make the fan wirings short/.so option B is also not advisable.but the problem is either in the thermostat or in the thermostat shut-off relay.the voltages needs to be checked by meter to confirm the fault. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Outdoor A/C unit fan

If the fan and compressor are shutting off. its possible its cycling on a low pressure switch. probably low on freon.

or you have a low ambient kit to keep pressures up during low outdoor temps while ac is running just the fan will shut off, however thats not a typical thing to have a residential system

Thermostat ?

I'm thinking the bi-metal is working, that's why you can hear a click, but the contacts are welded together. The bi-metal doesn't have enough strength to break the weld. Time for a new thermostat.

Compressor starts and doesn't stop

Relay for the compressor may be stuck ( Contacts welded) both the fan and the compressor should operate at the same time. Have the relay(s) checked and possibly replaced.

Check if the condensar ( outside fan unit) is getting enough free ventilation. IF there is no free air flow you will mostlikely be triping the unit due to short cycling. Ie the unit is pulling its own discherge air causing the compressor to trip due to high back pressure
