Glad to have found this as my heater was showing no power and the display was dead. I have a 400 cf heater and this was the replacement control unit. I did some online search to learn how to open the unit and change the part and luckily it worked out and now we are back to using the spa heater again. Just make sure it fits your specific unit, turn off the gas line and the electricity before installation, and follow online instructions.

Replaced the original control panel on a 12 year-old Mastertemp 400. Fired up with no issues. My original panel would randomly have E01 errors but all the sensors tested good. This panel did the trick. Hopefully it lasts a few years, I’ll report back with any issues.

Unit is working fine and got the hot tub up again. No problems with it whatsoever. We'll update this post if there are reports of problems going forward.
