Laser 56 an 73 Main Circuit Boards

[hawkins111]

Circuit boards for Laser 56 and Laser 73 are becoming hard to find. My regional distributor has them on back order, but that has been for several months now. Ebay has a few now and then and they are very expensive. They are also “USED”, so they could have 1000’s of hours service time.

This will be the demise of this line of Toyo heaters. It happened the same way with the earlier line of heaters, i.e. Laser 55 and Laser 72.

The L55, L72 line, fuel pumps ran out before the circuit boards did. So far the fuel pumps are still available for L56 and L73, which is a good sign.

Just today 4/29/2026 I have been notified by the factory that they will no longer provide circuit boards for Laser 56 and Laser 73 heaters.

There are some circuit boards for sale on Ebay at this time. You have to be careful buying used circuit boards, as the operating relays could be burned from long service.

Heater PC Repair in North Carolina used to repair Toyo boards, but they don’t do it any more.
