AMETHERM - SL32 1R030 - NTC THERMISTOR, 1 OHM, -20% TO +20%, RADIAL LEADED 5 5 3 3
Perfect for HVAC motors This thermistor works perfectly for replacing the burned up SG379 thermistor in my Trane furnace GE 1hp ECM blower motor. June 4, 2015
thermistor use as a replacement in motors, part costs 2% of the replacement motor cost March 5, 2015
Fixed my ECM Motor Module (HVAC) and saved $1000 I contacted RTI Electronics (manufacturer of the SG379) and got the specs for the SG379. It's a 1ohm 30amp Inrush Current Limiter. Same as their SG405 or the more readily available SL32 1R030 from Ametherm. I bought the SL32 1R030 from Newark for $2.36 and $6.22 shipping. Received in two days. Just swapped out the faulty component two hours ago and am now basking in the cool air once again. Can't believe a $2 part saved me from spending $1000. I had an HVAC tech come out to confirm the problem before attempting to fix ("easter egging" on your own is not safe), signed up for their service plan for $236 (includes free troubleshooting and two service visits for routine maintenance. I will now have them back to check over the system as part of the plan. Working on an HVAC system is dangerous and I would not recommended it to anyone. I was an electronics tech in the Marine Corps and had help from a licensed HVAC tech. Stay safe, get help. You can still save a bundle. As a side note I also purchased the VZPRO from (Zebra Instruments) surge protector for my GE motor since the motor and motor module is so incredibly expensive. August 2, 2012
