Aircraft
At approximately 1;500 feet AGL; while attaining final flap configuration; the nose up trim quit working. I asked the Capt to try his trim switch to see if it would trim nose up and it would not. I bumped it forward to see if that worked and it did. The aircraft was a little nose heavy; but still fully controllable; so I elected to continue and land instead of going around and asking the Capt to try and trim manually during another approach. The flare and landing required more back stick force than usual due the out of trim condition; but it was completely controllable and the landing was normal. We submitted a maintenance write up; and I believe the Capt followed it up with a verbal to [Maintenance Control and required company notifications.]
Below 1;000 ft; elevator trim became intermittent for FO (First Officer). Captain's elevator trim only worked one direction.
B737 flight crew reported an electrical trim malfunction on short final.
