We have new replacement Temperature Sensor kits used on the ID-1490, ID-4001 and ID-5001. These are new parts and are not 'New-Old' stock. This is a rebuild kit to replace your existing, non-functional Temperature Sensor.
These are equivalent to Heathkit's P/N 100-1727 and 100-1728.

Simply cut off the old sensor and replace with our kit. Seal with GE Silicon Seal for a waterproof seal.
