I changed clicks and relays but wires at the compressor burned,only fan runs but compressor still cant start,whats wrong and where is the thermostat?

How is temperature controlled, refrigerant pressure? Thermostat? Does the top of the compressor get too hot to touch?

Unless you are changing the compressor don't change any wiring. A live phase comes from the thermostat which goes to the c (common) and the neutral phase goes to a relay which sits over s (start) and r (run.) It doesn't matter if the live and neutrals are reversed.

Take off the service panel and check for the compressor running. Can you place your hand on
it or is it too hot. If it is you might change the relay to the compressor.Take your model no. to your local parts store and they will help you look at the part and exactly where it is located (on the compressor) Easy change out.
If the compressor is not running at all then remove the two wires to the thermostat and plug them
together (They will plug together if you turn one backwards and plug it into the other.)
Make sure you have unplugged the freezer while you are doing this.
Now you have routed around the thermostat.
If it runs then replace the thermostat and youre done!
If not after the relay and thermostat check it wont run then you have a bad compressor.
On the relay ask for a hard start relay for a freezer or ref. at the parts store. They know exactly
what it is. Its even easier to install. Don't be shy to repair this. You can do it or condemn it

Please rate me if this helped.

here is a link the manufacture. There is a some information  and manuals posted there. it looks like you may have a something like what they call a 335-935 http://www.caravell.dk/ Their manul at the bottom of all the languages shows a picture of the compressor and the thermostat device and knob. The cooling unit wiring should involve fans, lights and compressor. Compressor will have cutout safety and temp switches as well as the thermostat. and a capacitor. maybe but not likely a relay. It should all be visible around the compressor. Some starting devices may be on the compressor under the plastic cover where the wires go in. If any of those are bad and you do not have a warranty a hard start kit for $18 will replace all the starting components if that is what you need. Let me know if this gets you what you need or have more questions just ask.

first of all are you sure its running correctly,if its overly hot to the touch is may sound like its running which it may be,but only on the start/run windings and if left this way it will burn out soon,it needs start/run windings to oppose the pressures inside the compressor to get it up to correct operating speeds,then the start winding cuts out of the circuit,this is where the ptc overload comes into play,as it does this sequence switching to make it operate correctly,just unplug it from the compressor and plug in a new one,also you may think you hear the compressor running,but its only the fans in the unit running,a compressor will run warm but shouldn't be overly hot to the touch,then if this isn't your problem,it could be an evaporator core blocked by ice and you cant get cold thru a solid block of ice so iuf its a self defrost model the defrost thermostat or defrost heater might be inopertive too

Make sure you have 120volts at relay if not jump out thermostat if it starts to run and stays running Replace the thermostat. If you have 120volts at relay and it is not running or it's kicking off and on replace Start Relay/Overload but a bad compressor can make a Start Relay go bad so if you have the same Prob. after replacing Start Relay/Overload Compressor is bad

Compressor is bad the clicking noise is the Start Relay/Overload is kicking on and off. compressor is warm because it's trying to start but can't Frigidaire is known for bad compressors. I don't think the Start Relay/Overload is bad because the compressor gets warm.

Hi, the clicking you are hearing is the compressor overload/external overload. When your compressor is a burn out or you have a locked rotor which means the compressor has died on you, it gets very hot from trying to start and this relay which is tied into the common side of the common terminal on the compressor, will click on and off as the unit tries to start. I have repaired these units for years and know exactly what is going on and the unit is older as you say. I would suggest pricing a new box as changing out the compressor, you are looking at around $1800.00 and up. I hate to tell you this but this is the problem. If you want to confirm this, just pull the unit out from the wall and try to leave it plugged in. Remove the lower panel to excess the compressor, condenser fan motor, and coil. Just be careful as this compressor should be very, very hot when you put your hand on it. Then you will know that is the problem. It should be warm and running. Please keep me posted and I hope I have been of help to you. Didn't want to give you the bad news though.
Good Luck, and Sincerely,

If all fans are running, but not compressor You could try to install 3 N 1 start kit, thats might help 50/50. If it will start compressor - be ready for compressor to go out soon. might work for a year.

Set the thermostat to the coldest and check if there's power to the compresor relay , if yes the relay or the compresor are bad (in this case replace the relay which is the cheaper first step ,but if the compresor still won't start probably is burned out) If there isn't power to the compresor put a jumper wire to the thermostat if the compresor runs replace the thermostat.
