Ronaldo doubled United's lead after 32 minutes, heading in Alex Telles's corner. But Kieran Dowell's header from a Teemu Pukki cross reduced the arrears in first-half added time.
Dowell then turned provider for Pukki with a sublime reverse pass to allow the Finn to slot home Norwich's equaliser seven minutes after half-time.
Norwich were denied a third by David De Gea's superb save from Milot Rashica's shot.
Ronaldo completed his hat-trick to secure the points with a fierce free-kick 14 minutes from time.

Spurs struggled to break down the visitors throughout the contest, although they improved in the second half, with Son Heung-min's goalbound shot was blocked by Joel Veltman.
Graham Potter's side, who had beaten Arsenal last time out, themselves threatened when Hugo Lloris was called upon to deny Tariq Lamptey's effort and a Lewis Dunk header.
The breakthrough arrived in the final minute of regulation time, Trossard pouncing on hesitant defending to turn Eric Dier and poke in from close range.
Substitute Steven Bergwijn passed up a good chance to equalise in added time but Brighton held on for victory.

After a lengthy stoppage due to an injury to Burnley's Ashley Westwood, the Clarets, managed by Under-23 coach Michael Jackson following Sean Dyche's departure on Friday, took a 33rd-minute lead.
Weghorst headed the opener in from close range after Jay Rodriguez had hit the bar.
Maxwel Cornet missed a chance to double the visitors' lead in first-half stoppage time, firing a penalty kick wide after being fouled by Lukasz Fabianski.
They were eventually made to rue that miss 16 minutes from time as Soucek bundled in an inviting Manuel Lanzini free-kick from close range.
West Ham could have won late on, but Nick Pope produced a stunning save to claw out Issa Diop's header and denied Michail Antonio soon after.
The result takes 18th-placed Burnley up to 25 points, three below Everton who have played a match fewer.
West Ham are seventh, five points off the top four.
●Bruno Guimaraes scored his second goal of the match deep into second-half stoppage time as Newcastle United beat Leicester City 2-1 at St James' Park.
The visitors broke the deadlock on 19 minutes when Ayoze Perez flicked a corner into the path of Ademola Lookman to fire beyond Newcastle goalkeeper Martin Dubravka.
Leicester's lead lasted just 11 minutes as Guimaraes beat Kasper Schmeichel to a loose ball to poke in from close range his first home Premier League goal.
The second half started in end-to-end fashion, with Kiernan Dewsbury-Hall and Joelinton both flashing efforts wide of the target.
In the fifth minute of stoppage time, Guimaraes won it. Substitute Joe Willock surged forward on the counter-attack and eventually crossed in for the Brazilian midfielder to head high into the net and complete the turnaround.
Having stretched their home unbeaten run to seven matches Newcastle climb to 14th on 37 points, three adrift of ninth-placed Leicester.
