LEC F FREEZER CLICKING ON OFF

[fasetester]

hi guys i was rung up about a LEC fridge freezer. model T450cw the said it is clicking on and off. every ten sec or so could some one give me any pointers what the problum could be. as i have to check it out tomorrow morning. thanks fasetester 🙂

Re: LEC F FREEZER CLICKING ON OFF

Sounds like start relay on the compressor,could be a failed winding but you would need to check via the pins on the compressor.

Re: LEC F FREEZER CLICKING ON OFF

thanks sims for your reply i should get a reading across all the pins on the compressor. what reading should i get. and is there any way to test the relay. is there a over load on the relay. if it is tripping out what would cause it. thanks fasetester. 🙂

Re: LEC F FREEZER CLICKING ON OFF

Three pins in a triangle when you have removed relay,relays are often burned or fall to bits and then it will be obvious but you need to check the windings,one is the run winding one is the start winding the other pin is common to both, measure the readings from the top pin to each of the side pins,add those together and then measure across the bottom two,that reading should match the total of the other two.Readings depend on the size of the motor but should all measure up in the way described whatever their size.
There is a cut out usually in with the relay depending on the age of the appliance.

Re: LEC F FREEZER CLICKING ON OFF

only getting back to you now my neice died why would their be a capactor connected across the relay it seems a bit strange is their any way to test a dandyfoss relay it looks ok not burned thanks fasetester

Re: LEC F FREEZER CLICKING ON OFF

you shud get a reading across the three pins on the compreser aswell if not duff. :l: sad to here that

Re: LEC F FREEZER CLICKING ON OFF

Hi fasetester.
The capacitor is to help kick start the motor. On the pins on the compressor to give you an idea you should get something like for example, 28ohm from common pin at the top (or bottom cant remember what way round they are on Danfoss) to one of the other pins. Then 26 ohm from common to the remaining pin. The higher resistance reading (28ohm) will be the start winding the other (26ohm) will be the run winding. If you measure between the run and start pins you should get a total of the two readings 54ohm. There should only be 1 or 2 ohm difference between the run and start windings. Also check each pin to earth too. I use a test cord to by pass the starter and run the compressor but thats a whole new explenation. A pattern start relay is a few quid so may be worth just trying one.

Hope that helps.

Re: LEC F FREEZER CLICKING ON OFF

thanks subs for your reply. how do you make up a test. lead would a blockage in the lines cause this. like a back pressure the compressor goes to start then it shakes and stops. thanks fasetester 🙂

Re: LEC F FREEZER CLICKING ON OFF

if youd fitted a new comp. an not brazed it rite that could happen

Re: LEC F FREEZER CLICKING ON OFF

thanks guys for your help so far the relay is ok i am going to change the capactor i cant see the rating on the capactor. could you please tell me what capactor i should use uf rating the compressor is a TLEs6F thanks fasetester.
