The fuse link is a device that will open when over heated. If the exhaust temp is to high it will open and is a one time device. It can not be reset it must be replaced with a high temp fuse link made for the exhaust location. It will have a red mark on it indicating high temp.
Low gas pressure can cause a lean fuel condition that may cause the exhaust temp to rise enough to trip the link. I would also check for scale inside the heat exchanger. Scale inside the heat exchanger will not allow for proper heat transfer to the water, this will cause excess heat to be present in the exhaust. Proper water balance and flow are very important.

Low refrigerant or a bad sensor. Need a pro to look at it.

Your unit is more than likely going into Defrost mode. The defrost sensor is mounted to the coil, should be down low on the right. You should get a new sensor and replace it. You have already replaced the board so the sensor is either bad or you may have another issue.
If the fan is not operation properly you are not getting proper air flow thru the coil, the coil can then freeze.
If you are operating the heater in very cold weather it could freeze.
If your coil is not clean and air can not flow thru the coil it will freeze.

The low temp device is mounted inside the intake down below. Remove the large panel at the bottom, about a dozen 5/16" screws from the front. You will find the fusible link mounted to the back wall.
The second one is mounted in the exhaust near the top on the left side. Remove the top plate of the exhaust, 4-5/16" black screws and look down inside about 4 to 5 inches, on the left. The exhaust is the high temp fusible link.
You can test them with a meter to see if they are open or closed. I would focus on the exhaust link first and sometimes you can jump the link out to test the circuit. Only jump to test and not for usage or operation of heater.

Buy your self two new sensors, they are both the same. If your system if reading sensor open when disconnected from the board then your new sensors should do the trick.

Need a new controller. May be cheaper to upgrade to IAquaLink and control through a smart device with the app
