I have a 10 year old LD250, that stopped working for a few days last week. I checked all the safety devices, and voltages (I have an industrial maintenance background), all seemed fine. Turned the unit back on and it fired, the only problem is that I have to set my temp pots much higher to get the unit to fire up. Before the incident the temp pot was at about a 2 o'clock position to maintain 80 degrees, now it is at the 5 o'clock position just to fire. Any insight?
Also I was wondering if there is a way to convert this unit to a digital control?
