Very satisfied Thanks

Fixed a overheating issue (OH and OOH) errors

I had a bad heater relay that would stay on until the unit tripped on high temperature (OH or OHH). This replacement fixed the problem and I had no problem swapping out the old control. It came with new standoffs which were needed after the old ones crumbled on removal. It also came with good instructions.

Great help from Brianna!

Brianna diagnosed the problem correctly and sent the correct part and I methodically connected motherboard, it works great!

Works Great

Easy to install and works good so far.

Excellent technical support was extremely helpful

I ordered a new control board and it was shipped promptly. I reconfigured the wiring to match my old board and installed it, but the new board sill wouldn't start the heater. After a few calls to tech support, they were able to determine that I had plugged the control unit into the wrong connector at the control board. After that, everything worked great.
