NCVT1 Recall

Klein Tools is issuing a voluntary product recall on the NCVT1 in our Test and Measurement Line due to a potential safety hazard.

Why Is There A Recall?

It has recently come to our attention that one of our products, the NCVT-1 NONCONTACT VOLTAGE TESTER, has a potential safety issue that Klein Tools would like to rectify. The on/off button of the NCVT-1 is intended to be pressed down and then released. If the button remains depressed during the power on or power off cycle, the tip of the tool remains illuminated in green, indicating the tool is "ready to detect voltage," when it is not.

These affected products are sold in the following SKU numbers:

NCVT1 69149
NCVT1SEN 80018
NCVT1EP 80023

This recall involves Klein Tools Non-Contact Voltage Tester with model numbers NCVT1 bearing date codes ending H7. The product was also sold in variations and kits listed above, all bearing date codes ending in H7.

Frequently Asked Questions

When will I receive my replacement tester?

The NCVT-1P is now available and has started to ship. This is the model that replaces the NCVT-1. You can also check the status of your recall return by using the link below.

How can I tell if the product I have purchased are subject to this recall?

This recall only involves Klein Tools Non-Contact Voltage Tester with model numbers NCVT1 bearing date codes ending H7. All other active voltage tester models or NCVT1 with a date code other than H7 are not subject to recall.

I bought the NCVT1 as part of a kit. What do I do with the other pieces?

Other items in kits where NCVT1 was included, are not being recalled. These items should not be sent back for replacement and you can continue to use them.

Can I get a refund?

We will provide a replacement product as per recall regulations.

I really need this tester to do my job. Is there any way I can get my new NCVT1 sooner?

In order to comply with recall regulations we must receive the recalled unit back to ensure that it is no longer in use, before we can send out a new meter. Once we receive your returned unit, you will be sent the replacement unit when it is available.
