If I refinance my home to a new primary mortgage, is the interest from that loan deductible under the new tax law for 2018 taxes?

I have a home equity line of credit on my primary residence. Interest is deductible for 2017, but under the new tax law, interest from that HELOC is not deductible for 2018 taxes. If I refinance the home with a new primary mortgage and pay off the HELOC, is the interest from that new loan tax deductible for 2018 taxes?
