Hi, there are a couple of things that will cause your air handler to ice up, some you may be able to take care of your self, and the last you will need to call out a service tech. First of all, you must have a clean filter at all times. 2nd, if the indoor coil has gotten dirty, this will cause decreased air flow across this coil and it will ice up very bad. Cleaning or I should say, getting to this coil to clean can be a job. You will have to bend the sheet metal panels, remove some screws, and work around the freon lines to get back to it enough to remove the sheet of dirt that is covering the coil. It will peel off like a sheet. When they get this way over the years, they will block the return air back through the coil, and it will ice up.Once it is cleaned, you may have to buy a roll of aluminum tape to seal the areas that didn't go back together very good. If your blower motor is not moving air very good, like it is ready to go out, moving slow, or making noise, this will do the same. The last thing that will cause this, is the unit has a small freon leak. If your air handler is gas, you can turn on the heat to melt the ice off faster, if not, turn just the fan on to melt the ice away. Once its gone and you have good air flow, turn the a/c back on and go to the outdoor unit. Place your hand above the fan guard to see if the air is good and warm to hot. Find the large copper line below and grab hold to make sure it is good and cold and is starting to condensate. The smaller line, discharge should be good and warm to hot. This will tell you the freon level is real close to being full, so your problem will more then likely be a dirty, plugged indoor coil. More then likely, this is your problem and would be something you could do your self to save you $$$$. I hope I have helped you on this and given you some direction to go on. I have done this for many years, and know the signs very well. Please don't forget to rate me as I know you will be kind. Please keep me posted on the outcome.

Yes. The coil voltage, number of poles must match. And if it fits a socket, the pin configuration also.

What is the output for a Nordyne Model B5BM-X36K-B (via google search)

Looks to be about right. This is an older unit. Have you had it checked or serviced? I'd guess you have a freon leak and it will not work without the right amount of "blood". Or filter's havnt been chanded, or filters failed sometime and the coils are "clogged" especially if house had pets. Your careful inspection should revel those problems. If no problems and not been serviced recently call HVAC tech.

Can you see the condition of the coil itself? If it is blocked this could be a cause for the frozen coils. Also, check the condition of the blades on the indoor fan. Dirt and dust accumulation on the blades reduces airflow.

My air handler sprung a leak and needs to be replaced. Would it be a bad idea to use a Lennox CBX32MV-048 variable speed air handler or is it better to get a carrier air handler?

They are expensive to buy, and to replace it as well. I would not to expensive. Any air handler, just not a variable speed.
