SH1500 heater. First off, one of best purchases I've made. Really like how it works. But had to order a new on/off for the 2nd time. Just stops working for no reason at all. I do not turn it on and off a lot. Either the switch is on or off. Why does it keep going out? Thanks

Bad on/off switch on sun heater
Remove the screws from the back of the heater that hold the heat box in the wood casing. Then remove the support brackets from the left and right sides that you can see on the back. Then remove the one long screw from each wheel bracket on the bottom. Flip the heater back up right and pull the whole metal heat box from the wood case. Lay the heat box on its left side and remove the screws holding the right side cover on. Note the location of the wires on the old switch and them remove them from the switch. Squeeze the upper and lower tabs together and push the switch out the front. The use of pliers may be required. Assembly is the same but in reverse. Use caution tightening screws as to not to over tighten them. The metal screws will strip very easily. Good luck and have fun.

My grand son played with the switch until it broke.
1. Took the inside heater out of the wood box by following the online instructions.
2. Unscrewed the metal side by removing 20 + or - screws were the switch was.
3. Found the switch that needed replacing
4. Ordered the switch and after one week it arrived
5. Unplugged to broke switch and replaced the wires on the new and pressed it into place
6. Reassembled the whole Heater.
7. Plugged it in and voila. It worked like new.

Thank you.

Took case off the heater, took panel off side, took old switch out and Put new switch in and connected using the diagram we made. Most difficult step was putting new switch in....and we were probably being overly careful!

    Thank you for having the right pieces for my heater, not knowing where else to find the parts, you sent it sooner then I thought it would come. Fixed and running.
    Guest - April 28, 2019 Verified Purchase
    quick delivery but This switch didn't work either
    I installed the switch -- not hard because i already replaced one a couple years ago. BUT, this one doesn't work either. So I'm just using the thermostat dial to turn the unit off and on now.
