1980's Hotpoint stove digital clock problem

The first step would be to test whatever fuses there might be. You don't need a million dollar meter. A simple automotive circuit tester would do the trick.

getting one right now takes effort due to the pandemic lockdown here. Before I put in the effort to order more fuses to replace potentially blown old ones, I need to know if the display is off because of a blown fuse, or is the clock / temp control beyond repair.

I wouldn't use a simple automotive circuit tester because auto is 12 volts and the stove clock is potentially 120/240.

Check the fuses first. Did you recently have a power event? You could try "rebooting" the stove by disconnecting all power for a minute or so then re- powering. REport back your progress.

A 40 year old stove may not be worth repairing, even if there are parts available...

Don't know about HotPoint - but had the same problem on Frigidaire and was lucky to get one of the last three display modules 3 years ago and had the timer/control rebuilt by the company in Montreal PQ who had the forsite to have had a batch made several years previous. They said when those 3 were gone they were no longer repairable as they could not get any more of them produced (vacuum EL display)

If you remove the fuse, it is no longer 120, nor is it 12, nor 12000. Take the fuse out and check continuity with any tester of any voltage.

I don't know why a fuse would blow suddenly though. The fuses in my stove run the outlet not the controls, so I could blow them by plugging in a coffee pot maybe, but in your case I would think it might be the display gone.

I think Dean meant to check the fuses when they are out of the circuit. A lot going on here, like are fuses blowing and if so, why. If it needs a new display, poster can find the price for one, if it's still available at all. Given the price of parts and the age, a new stove is probably the right option.
