If it's an appliance module it is not an 8741, no module I've ever seen has (or needs) a 40 pin DIP. Aside, I have a lamp module that died. Some modules (light switch) have a fusible link which blows. This one doesnt seem to. Is there any protection device in these which I can repair? If not, does anyone know if BSR will still swap these things for a nominal charge? Does anybody have an address to get these repaired? It is an older Sears type (300 watt/brown), not the RS "cost-reduced" kind. Ron Fletcher AT&T Bell Laboratories Middletown NJ att!mtuxo!mtgzy!rlf
