Frigidaire 5-heat Radiantube wattage & wiring

I thought that the mac.com email service was long gone.

"@mac.com" email addresses are still valid, I've had mine for about 10 years now.

Sorry didn't mean to hijack this thread for an infinite control issue....

But... I was able to find a replacement infinite control for this range online. PC Appliance Repair had it for only about $25. Ordered one just now.

Getting at this was a bit involved. First, tripped circuit breaker to range. Removed three big flat head screws under the control panel with oven door opened. Then removed all burner trays, supports, and trim rings, and burner/oven knobs. Unscrewed the screws holding the top down. These were in each burner hole in the top. Some had more than one. Then, removed two screws from the oven control and two from the right rear burner control - these were holding the brushed chrome cover over the control modules and wiring in place. Removed chrome control cover. Labeled all the wires to the left front 8" burner control. Pulled these wires from control. Also pulled two wires leading to the "Surface" pilot light, and four wires leading to the Oven/Lock pilot lights.

Apparently there's been some water damage/rusting issues with the control. Probably because it's closest to the front burners. The oven control also shows some rust issues, at least on the attachment screws, but I'm not too concerned about that just yet (never have used that oven).

I'll probably wind up spritizing the defective control with Electromotive cleaner and re-installing it to see if that freed up whatever might be stuck inside. I have to put it all back together anyway... because oddly the electric cooktop in the main house kitchen is on the same 50 amp 220 volt circuit. Yes, I replaced that cooktop with a gas unit, but it's using one of the legs of the 220 for a 110 volt outlet to power the burner igniters. I suppose I could run an extension cord to it but I'd rather not. Plus I'm curious to see if the cleaner works.

Should have the replacement part in a week or so.

PS-Cleaning and blowing out the control didn't work. Burner works ok on High and medium, but not on simmer to lo. So it must have some sort of internal broken connection. Easier just to replace it at this point. Other burners work fine.

I didn't measure the resistance. I was looking for continuity or no continuity in the burner element.

I assumed that I'd isolated the problem when there was voltage available to the burner and zero continuity with the switch off.

I saw nothing that looked like a fuse or fusible link when I withdrew the fold-up burner assembly. I would think that if there was a short to ground that a breaker would have tripped. I think what I need to do is locate a good replacement burner.

If anybody has a spare radiantube burner that they are willing to part with I have a lady who could use it.

thanks

Hello. For 1958 (could be 1957, but much more likely 1958) Frigidaire Fold-Back Surface Unit, model RBZ-84, consisting of models RBZ-81 and RBZ-82, I want to repair or replace, if possible, Std. 6- and 8- inch Radiantubes in RBZ-81, and 6-inch Speed-Heat Unit and 8-inch Heat-Minder Unit in RBZ-82. Does anyone have wiring diagrams, parts, suggestions? Thank you.

Hi Dan, 

 

Welcome here. 

 

Here's a link to a high quality scan of the service manual that's available here. There's a small download fee but it might be useful for you to get it!

Thank you very much for the link, Phil. I've downloaded the relevant Frigidaire Service Tech-Talk document. Dan.

You're welcome!

 

Keep us informed of if you find what's wrong with the help of this document.

 

You can probably convert these elements so they work like those in your RBZ-81 as parts for them are easier to find. And it's never too late to go back to the original Heat Minder and Speed Heat if you find the correct replacement parts later!
