Hi folks, need too replace my PS I have found that there are two options. One is the original part #437238, and the other is a replacement part #5007356. Will one be better than the other? The price for the first part is about $10-20 cheaper. When it comes down to it im cheap. Was there a problem and that's why they changed parts. Oh, the reason I need too replace the PS is it does not activate when I press the key. There is power going to the noid but no action. Thank you...
