driveway heater
hi,
this is pretty vague -- it is a 30 y/o driveway heater (to melt snow) that turned on spontaneously for the summer. the power switch (for the user) was in the off position however apparently it is (was) controlled by an inhibitor of some sort which broke. question: could a power surge (for example after a power failure) damage the an inhibitory item and cause it to malfunction (or not function)? apologies again for being vague thanks |

Next time, make sure the breaker or actual physical switch for the device is off in the summer! --- sam | Sci.Electronics.Repair FAQ Mirror: http://repairfaq.ece.drexel.edu/ Repair | Main Table of Contents: http://repairfaq.ece.drexel.edu/REPAIR/ +Lasers | Sam's Laser FAQ: http://repairfaq.ece.drexel.edu/sam/lasersam.htm | Mirror Sites: http://repairfaq.ece.drexel.edu/REPAIR/F_mirror.html Note: These links are hopefully temporary until we can sort out the excessive traffic on Repairfaq.org.

Next time, make sure the breaker or actual physical switch for the device is off in the summer! thank you very much for the reply! it is a power-hungry monster. the switch (the user's switch) and the control-box switch were off however the breaker (in the fuse box) was not activated sincerely Tanya --- sam | Sci.Electronics.Repair FAQ Mirror: http://repairfaq.ece.drexel.edu/ Repair | Main Table of Contents: http://repairfaq.ece.drexel.edu/REPAIR/ +Lasers | Sam's Laser FAQ: http://repairfaq.ece.drexel.edu/sam/lasersam.htm | Mirror Sites: http://repairfaq.ece.drexel.edu/REPAIR/F_mirror.html Note: These links are hopefully temporary until we can sort out the excessive traffic on Repairfaq.org.
