Think I fried my control board?

[Catch22]

Hello,
I'm new to the forum and I could use some help. I have a gas overhead garage heater and I was removing the limit switch on it and I forgot to unplug the heater, when I was removing the limit switch it sparked on the metal housing now nothing works on the heater.
Do you think I fried the control board?
The heater is a Cayenne 45000 btu.

Thanks Mike

I would look to see if there's a 24V fuse or test the transformer.

Thank you...
