Re: Hotpoint Minstral FF72P PCB part PTC1?
Hi All,
First time using a forum, hope I am posting this in the correct place. I have a Hotpoint FF92S which the fridge section is staying at ambient but the freezer is working fine at -22. I have read various threads through this forum and managed to isolate the fault to the PTC on the control PCB. I read in a post that the PTC can be shorted out to confirm that it was faulty. I did this in the same method that what mentioned, using some 5amp fuse wire and shorting out the PTC legs. I put the fridge on to run waited for about 20 minutes or so for the freezer to come down in temp. Once the freezer reached -10 I opened the door and to my satisfaction I finally had cold air coming up the tube and in to the fridge compartment. I thought great, I can now order the PTC from RS and the job will be done. I left the short on the PTC as did the guy who put the post on but after about a couple of minutes from opening the door there was a pop. On investigating I could smell the dreaded burning smell of a component failure and found that TY5 has popped on the PCB. It comes of one of the legs from the PTC and I assume it is altering current flow when the PTC’s resistance is changing. The markings on TY5 are Z7S Y150 but I am unable to match it with anything? Can anyone help as to identifying this transistor? where can I get one or an alternative? Thanks in advance for any help.
