Product Overview

The SL32 1R030 is a NTC Thermistor with radial leads. It is specially designed to withstand up to 30A of continuous current and 270J of input energy. It absorbs high amounts of inrush current when electrical equipment is turned on by offering a high resistance to current and quickly decreasing in resistance once steady state current begins to flow through the thermistor.

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
