My gas fireplace control has a manual and thermostatic control. The temperature can be set and the fire starts automatically, or use manual control and press once for high, press again for low. Neither manual nor automatic is functioning.

Hi bcottage and welcome, can you post a make and model number? I'll see if I can help.

Control is Heat-n=Glow WSK200-HNG, Originally there was a manual start, High, Low, Off, and a thermostatic control that would maintain a set temperature, The manual control stopped working, and we used the thermostatic control. Now, we get no results from either. Also, blower control had three settings, now inoperative. Any ideas?

Control is Heat-n=Glow WSK200-HNG, ?

This no. in on a wall switch? Have you checked the power to the switch?
